3 Seals Choice of the Sealing Element Sealing elements have a decisive influence on the design, function and service life of hydraulic and pneumatic cylinders and systems. This applies equally to the piston rod seals where leak tightness, resistance to wear and gap extrusion, resistance to process media, resistance to high and low temperatures, low friction, compact form and simple installation are demanded in order to meet the requirements of industry for a functional sealing solution. The significance of these parameters and their limits is generally dependent on the requirements of the specific application. B+S has therefore developed a complete range of seals which, due to their optimized geometries and designs and the use of highquality materials such as TurconR and ZurconR, satisfy the technical and economic demands of the industry in full. In order to be in a position to select the most appropriate seal type and material, it is necessary to first define all the desired functional parameters. Table I can then be used to make an initial selection of seals and materials according to the specific requirements of the application. Note on Ordering All multielement standard rod seals, e.g. TurconR StepsealR K, are generally supplied as complete seal sets. The supply includes the seal and matching elastomer energizing elements. The ORing does not have to be ordered separately. It is also possible to use other ORing materials from our ORing catalogue. In this case, please order the seal ring and ORing separately. Older designs of seals no longer contained in this catalogue naturally continue to be available. For all new applications, however, we recommend the use of the seal types and preferred sizes (ISO series, wherever possible) listed in this catalogue. Other combinations of TurconR materials and special designs can be developed and supplied for special applications in all intermediate sizes up to mm diameter, provided there is sufficient demand. The sizes contained in this catalogue are mostly available from stock or can be supplied at short notice. We reserve the right to modify our supply programme. The second column of the table contains the number of the page on which further general information together with specific design and installation instructions on the particular seal type and materials (or material combinations with multielement seals, e.g. TurconR StepsealR K) can be found. Furthermore on page 11, attention is drawn to the quality of the mating surface. We recommend that the limits specified there be observed, as they have a decisive influence on the functionality and service life of the system. The final choice of seal type and material must also take account of the detailed information on the seal elements. Please do not hesitate to contact our Technical epartment for further information on specific applications and special technical questions. This Catalogue is a compilation of the preferred product ranges of Busak+Shamban, Sealing Parts and POLYPAC. All similar products are technically equivalent but availability and pricing may vary.

6 Seals Redundant Sealing System Sealing of environmentally harmful fluids has led Busak+Shamban to develop innovative sealing systems to meet the ever demanding industry specifications with regard to leakfree performance and high service life. In heavy duty applications, leak free performance and high service life cannot be assured by a single sealing element; therefore, specially developed system seals are arranged in series, building a tandem arrangement. Each sealing element in a system has its specific function and their interaction needs to be secured to get a redundant sealing system. The primary seal in PTFE based proprietary TurconR material generates low friction and has an excelent wear and extrusion resistance under extreme working conditions. It allows a fine lubrication film passing this first barrier, ensuring the necessary lubrication of the secondary sealing element for long service life. Busak+Shamban has pioneered work in this area and continues development of redundant sealing today. Outstanding solutions to such applications have been the TurconR StepsealR K in tandem arrangement. A tandem sealing system can also be created by using e.g. ZurconR Rimseal, ZurconR LCupR or UCup as secondary sealing elements. epending on type of secondary seal, a singleor double acting scraper completes the system, to offer the highest possible operation reliability, ensuring both adequate lubrication of the sealing system and a long service life. The figure 1 shows as an example a redundant sealing system consisting of TurconR StepsealR K, ZurconR Rimseal and Scraper A 22 with corresponding wear ring arrangement. The tandem arrangement requires an outstanding backpumping ability of the primary seal and the secondary seal, if a double acting scraper is installed. A combination of different sealing materials in a system, TurconR and ZurconR, (PTFE and Polyurethane) ensures the best sealing performance.

7 Seals esign Instructions Leadin Chamfers Table IV In order to avoid damage to the rod seal during installation, leadin chamfers and rounded edges must be provided on the piston rods (see Figure 2). If this is not possible for design reasons, a separate installation tool must be used. Leadin Chamfer iameter reduction d min. The minimum length of the leadin chamfer depends on the profile size of the seal and can be seen from the following tables. Additionally it is recommended that the diameter reduction d exceeds x rod diameter.

8 Seals Surface Roughness IN EN ISO 4287 The functional reliability and service life of a seal depend to a very great extent on the quality and surface finish of the mating surface to be sealed. Scores, scratches, pores, concentric or spiral machining marks are not permitted. Higher demands must be made on the surface finish of dynamic surfaces than of static mating surfaces. The characteristics most frequently used to describe the surface microfinish Raa, Rz and Rmax are defined in IN EN ISO These characterics alone, however, are not sufficient for assessing the suitability in seal technology. In addition the material contact area of the surface roughness profile Rmr in accordance with IN EN ISO 4287 should be demanded. The significance of this surface specification is illustrated in Fig. 4. It shows clearly that specification of Ra and Rz alone does not describe the surface roughness profile accurately enough for the seal technology and is thus not sufficient for assessing the suitability. The material contact area Rmr is essential for assessing surfaces, as this parameter is determined by the specific surface roughness profile. This in turn is directly dependent on the machining process employed. Busak+Shamban recommends that the following surface finishes be observed: Table V Surface Roughness Surface profile Ra Rz Rmr % % closed profile form open profile form Figure 4 Profile forms of surfaces Figure 4 shows two surface profiles, both of which exhibit nearly the same value for Rz in the test procedure. The difference becomes obvious only when the material contact area of the surface roughness profiles are compared. These show that the upper roughness profile with Rmr = 70% has the better seal/mating surface ratio. Hardware For optimum performance Busak+Shamban recommends a piston rod of chromeplated steel.

9 Seals Installation Instructions The following points should be observed before installation of the seals: Ensure the piston rod has a leadin chamfer; if not, use an installation sleeve eburr and chamfer or round sharp edges, cover the tips of screw threads Remove machining residues such as chips, dirt and other foreign particles and carefully clean all parts The seals can be installed more easily if the rod is greased or oiled. Attention must be paid to the compatibility of the seal materials with these lubricants. Use only grease without solid additives (e.g. molybdenum disulphide or zinc sulphide). Installation in Closed s By following the instructions in each seal type description (sizes for closed or split grooves) or using the light series for TurconR seals, it will result in a problem free installation of our rod seal elements at small diameters. For ZurconR and polyurethane (not TurconR) seals, the use of installation tools is to be recommended. If installation has to be performed without installation tools, however, the following points should be observed: Place the ORing into the groove (not necessary with UCups) Compress the TurconR or ZurconR seals into a kidney shape. The seal must have no sharp bends (Figure 6)! Use no sharpedged installation tools Installation in Split s Installation in split grooves is problem free. The sequence of installation corresponds to the configuration of the seal, whereby the individual seal elements must not be allowed to twist. uring final installation (insertion of the piston rod into the seal), elastomer or springenergized seals must be sized. The piston rod itself can be used for this purpose, provided that it has a long leadin chamfer, or use a sizing sleeve. Figure 6 Kidneyshaped deformation of the seal ring Place the seal ring in compressed form into the groove and push against the ORing in the direction of the arrow (Figure 7). Figure 5 Installation in a split groove Figure 7 Inserting the seal ring into the closed groove 12

10 Seals After placing into the groove, form the seal into a ring again in the groove by hand. Finally size the seal ring using a mandrel which should have a chamfer of 10 to 15 over a length of approx. 30 mm The sizing mandrel should be made from a polymer material (e.g. polyamide) with good sliding characteristics and high surface quality in order to avoid damage to the seals. The piston rod itself can also be used for calibration, provided it has a sufficiently long leadin chamfer.

11 Seals Installation of ouble eltar Installation in closed grooves is possible for diameters from 12 mm using the following procedure: Place the ORing into the groove. Compress the TurconR seal into a kidney shape, avoid making sharp bends on the seal (Figure 10). Place the seal ring in compressed form into the groove and push against the ORing in the direction of the arrow in the groove by hand (Figure 11). For diameters smaller than 30 mm an inserter tube is recommended (Figure 12). Finally, size the seal ring using a mandrel which should have a chamfer of 10_ to 15_ over a length of min. 30 mm (Figure 13).

Customers who require special quality criteria should contact their local Busak+Shamban sales office for assistance. We have experience in meeting all Customer quality requirements. Storage and Shelf Life Seals and bearings are often stored as spare parts for prolonged periods. Most rubbers change in physical properties during storage and ultimately become unserviceable due, e.g., to excessive hardening, softening, cracking, crazing or other surface degradation. These changes may be the result of particular factors or combination of factors, such as the action of deformation, oxygen, ozone, light, heat, humidity or oils and solvents. The standards give several recommendations for the storage and the shelf life of elastomers, depending on the material classes. The following recommendations are based on the several standards and are intended to provide the most suitable conditions for storage of rubbers. They should be observed to maintain the optimum physical and chemical values of the parts: Heat The storage temperature should preferable be between +5 C and +25 C. irect contact with sources of heat such as boilers, radiators and direct sunlight should be avoided. If the storage temperature is below +15 C, care should be taken to avoid distorting them during handling at that temperature as they may have stiffened. In this case the temperature of the articles should be raised to approximately +20 C before they are put into service. Humidity The relative humidity in the store room should be below 70 %. Very moist or very dry conditions should be avoided. Condensation should not occur. Light Elastomeric seals should be protected from light sources, in particular direct sunlight or strong artificial light with an ultraviolet content. The individual storage bags offer the best protection as long as they are UV resistant. It is advisable to cover any windows of storage rooms with a red or orange coating or screen. Radiation Precaution should be taken to protect stored articles from all sources of ionising radiation likely to cause damage to stored articles. With a few simple precautions, the shelf life of these products can be considerably lengthened. Fundamental instructions on storage, cleaning and maintenance of elastomeric seal elements are described in international standards, such as: IN 7716 / BS 3F68:1977, ISO 2230, or IN

14 Seals Oxygen and ozone Where possible, elastomeric materials should be protected from circulating air by wrapping, storage in airtight containers or by other suitable means. As ozone is particular deleterious to some elastomeric seals, storage rooms should not contain any equipment that is capable of generating ozone, such as mercury vapour lamps, high voltage electrical equipment, electric motors or other equipment which may give rise to electric sparks or silent electrical discharges. Combustion gases and organic vapour should be excluded from storage rooms alas they may give rise to ozone via photochemical processe eformation Elastomeric materials should, wherever possible, be stored in a relaxed condition free from tension, compression or other deformation. Where articles are packed in a strainfree condition they should be stored in their original packaging. Contact with liquid and semisolid materials Elastomeric seals should not be allowed to come into contact with solvents, oils, greases or any other semisolid materials at any time during storage, unless so packed by the manufacturer. AU, Thermoplastics 4 years NBR, HNBR, CR 6 years EPM 8 years FKM, VMQ, FVMQ 10 years FFKM, IsolastR 18 years PTFE unlimited Elastomeric seals should be inspected after the given period. After this giving an extension period is possible. Rubber details and components less than 1,5 mm thick are liable to be more seriously affected by oxidation degradation even when stored in satisfactory conditions as recommended. Therefore they may be inspected and tested more frequently than it is mentioned above. Rubber details / seals in assembled components It is recommended that the units should be exercised at least every six months and that the maximum period a rubber detail be allowed to remain assembled within a stored unit, without inspection, be a total of the initial period stated above and the extension period. Naturally this will depend on the design of the unit concerned. Contact with metal and nonmetals irect contact with certain metals, e.g. manganese, iron and particularly copper and its alloys, e.g. brass and compounds of these materials are known to have deleterious effects on some rubbers. Elastomeric seals should not be stored in contact with such metals. Because of possible transfer of plasticisers or other ingredients, rubbers must not be stored in contact with PVC. ifferent rubbers should preferably be separated from each other. Cleaning Where necessary, cleaning should be carried out with the aid of soap and water or methylated spirits. Water should not, however, be permitted to come into contact with fabric reinforced components, bonded seals (because of corrosion) or polyurethane rubbers. isinfectants or other organic solvents as well as sharpedged objects must not be used. The articles should be dried at room temperature and not placed near a source of heat. Shelf life and shelf life control The useful life of a elastomeric seals will depend to a large extend on the type of rubber. When stored under the recommended conditions (above sections) the below given shelf life of several materials should be considered. 17

16 TurconR StepsealR K TurconR StepsealR K escription The sealing of piston rods places the highest demands on operational safety and environmental protection in hydraulic engineering. seals must exhibit no dynamic leakage to the atmosphere side under all operating conditions and must be statically completely leak tight when the machine is at a standstill. Furthermore, they should achieve a high degree of mechanical efficiency through low friction and be easy to install in small grooves. Costs and service life must meet the high expectations of the operator. The piston rod seal, TurconR StepsealR K, developed by Busak+Shamban comes closest to satisfying these ideal demands. Already in use for several decades this seal is still a technically outstanding seal element due to the continuous innovative further development of the design and of the TurconR and ZurconR materials. With the introduction of the StepsealR K it was possible for the first time to arrange several seals one behind the other, thus allowing statically and dynamically tight, doubleacting tandem seal configurations to be created without any disturbing buildup of intermediate pressure. The singleacting seal element is made of highgrade TurconR or ZurconR materials with outstanding sliding and wear resistance properties. It is installed according to ISO 7425/2 and Busak+Shamban standard grooves, using an ORing as energizing element. ORing TurconR Seal ring p Figure 15 TurconR StepsealR K PatentNo. P Method of Operation The sealing mechanism of the StepsealR K (Figure 15) is based on the hydrodynamic properties of the seal. The specially formed seal edge with a steep contact pressure gradient on the high pressure side and a shallow contact pressure gradient on the low pressure side ensures that the fluid film adhering to the piston rod is returned to the high pressure chamber on the return stroke of the rod. This prevents the microfluid layer, carried out of the high pressure chamber when the piston rod is extended, causing leaks. This return delivery property prevents the buildup of intermediate pressure normally associated with tandem seal configurations (Figure 16) with primary and secondary seal. From our experience we know that the level of the pressure between the two seals does not exceed 10% of the working pressure. It depends on the speed, the stroke length and the groove design. Advantages High static and dynamic sealing effect Low friction, high efficiency Stickslipfree starting, no sticking High abrasion resistance, high operational reliability Simple groove design Wide range of application temperatures and high resistance to chemicals, depending on the choice of ORing material Simple installation without seal edge deformation thanks to the Kedge Available for all diameters up to mm Technical ata Operating pressure: up to 80 MPa Speed: up to 15 m/s with reciprocating movements, frequency up to 5 Hz Temperature: 45 C to +200 C (depending on ORing material) Media: Mineral oilbased hydraulic fluids, flame retardant hydraulic fluids, environmentally safe hydraulic fluids (biooils), water and others, depending on the ORing material Clearance: The maximum permissible radial clearance smax is shown in Table IX, as a function of the operating pressure and functional diameter Important Note: The above data are maximum values and cannot be used at the same time. e.g. the maximum operating speed depends on material type, pressure, temperature and gap value. 21

17 TurconR StepsealR K Materials esign Instructions The following material combination has proven effective for most applications: In many applications, secondary seal systems are demanded.

These are indicated by the series numbers. Table IX, shows the relationship between the series number according to the seal diameter range and the different application class sizes. These application classes are: Standard application: General applications in which no exceptional operating conditions exist. Light application: Applications with demands for reduced friction or for smaller grooves. Heavyduty application: For exceptional operating loads such as high pressures, pressure peaks, etc. Application Examples S S S S S S S S Mobile hydraulic Standard cylinders Machine tools Injection moulding machines Presses Automobile industry Hydraulic hammers Servo hydraulics P Figure 16 TurconR StepsealR K and ZurconR Rimseal in tandem configuration In this configuration it must be noted that a sufficiently large space is formed between the seals to take the hydraulic fluid, as shown in the figure. epending on the application and the operating conditions, the combination of different materials offers a further improvement in the sealing efficiency and the service life of the system, e.g. in hydraulic cylinders subject to high loads and under rough operating conditions, the primary seal should be made of TurconR and the secondary seal of ZurconR. StepsealR K elements should always be used in combination with a double scraper to provide an optimum sealing effect. The scraper TurconR ExcluderR 2, TurconR ExcluderR 5, ZurconR ExcluderR 500, A17 and A22 are well suited to such applications. For further details, please refer to our Scrapers catalogue. 22

25 R ZURCON RIMSEAL Single Acting Rubber Energised Plastic Faced Seal Material ZurconR 31

26 ZurconR Rimseal ZurconR Rimseal escription Method of Operation When the field of application and system requirements make high demands on leakage control and operational reliability, a redundant sealing system is necessary to ensure reliable sealing of hydraulic cylinders at the piston rod. Sealing systems with elastomerenergized polymer seals are a proven answer to widely varying demands for standardised grooves, simple installation, resistance to media, high and low temperatures and pressures. The system offers enormous flexibility in the choice and matching of materials. The ZurconR Rimseal is an elastomer energised seal element. The changes in seal position in the groove necessary for an optimum sealing function are guaranteed by the combination of the two component parts (ORing and seal ring). The piston rod sealing system for hydraulic cylinders subject to heavy loads should consist of three elements: In order to achieve a contact pressure curve which enhances the sealing effect, the seal has a chamfer on the low pressure side. When under pressure and exposed to friction against the piston rod, this chamfer causes the seal to tilt slightly so that the seal ring is forced against the side of the groove. This creates an area of maximum pressure at the edge of the seal. The proven TurconR StepsealR K used as primary seal. This seal element offers the back pumping property necessary for redundant rod seal systems as well as good resistance to high and low temperatures and high media resistance. When the ZurconR Rimseal is used in a system with a doubleacting scraper (A 22, A 17, ExcluderR 2 resp. 5 or 500), the sealing function of the system must be assured even if pressure buildup occurs between the ZurconR Rimseal and the doubleacting scraper seal. The ZurconR Rimseal was developed as the secondary seal in this system to ensure reliable sealing of thin oil films at low secondary pressures. A relatively soft material (polyurethane Shore 58) is used combined with a new seal profile. For this reason, the highpressure side of the seal ring also has a chamfer which, in the event of a buildup of pressure behind the ZurconR Rimseal, comes into contact with the flank of the groove. The ZurconR Rimseal moves in the groove so that a contact pressure distribution is obtained on the piston rod which enhances the back pumping effect. The contact pressure curve is automatically optimised under dynamic conditions. The final outer element of the redundant sealing system is a doubleacting scraper seal (e.g. A 22, A 17. TurconR ExcluderR 2 resp. 5 or ZurconR ExcluderR 500). The optimum sealing system thus consists of three independent lip seals installed in line, whereby the hardness of the material decreases from the pressure side to the atmospheric side.

Materials The ZurconR Rimseal is made in the following material combinations as standard: ZurconR Rimseal: ZurconR Z52 Special polyurethane 58 Shore ORing: NBR. 70 Shore A Set: Z52N or Z52T Series The ZurconR Rimseal is a system seal and is preferably used in tandem sealing systems in conjunction with the TurconR StepsealR K. For this reason. the type series are identical with those for the TurconR StepsealR K. Table XII shows the relationship between the series number according to the seal diameter range and the different application class sizes. These application classes are: Standard application RR13 Light application RR15 Heavyduty application RR11 esign Instructions Redundant sealing systems are used where the application conditions no longer permit reliable sealing over the demanded service life with a single seal. The property of the tandem sealing system is particularly important during cold starts when, due to the very high viscosity of the oil, the primary seal allows oil to pass as the piston rod is extended. In the tandem system the oil is heated as a result of the friction at the primary seal and is then reliably wiped off at a now lower viscosity by the secondary seal, the ZurconR Rimseal. As the piston rod is retracted, the oil is stored in the reservoir between the seals, and is then pumped back against the system pressure by the hydrodynamics in the seal clearance of the TurconR StepsealR K. Particularly with strokes of more than 1 metre, constructional measures have to be taken to provide a storage chamber between the seals. The ZurconR Rimseal is designed so that it also has the back pumping properties necessary when using a doubleacting scraper in the rod sealing system. ue to the controlled sealing behaviour of the individual elements in the sealing system and the appropriate combination of the seal materials, a rod seal system is obtained with a low overall friction. The figure 21 shows a redundant rod seal system consisting of TurconR StepsealR K, ZurconR Rimseal and Scraper A 22 with corresponding wear ring arrangement.

59 R ZURCON LCUP Single Acting Innovative esign based on UCup Low Friction Properties Material Polyurethane 69

60 ZurconR LCupR Introduction The rod sealing system is the most critical part of a hydraulic cylinder. Therefore it is expected that a rod sealing system performs under leakfree conditions in the static and dynamic state. Moreover it has to fulfil the lifetime of several thousand hours. To meet these requirements, Busak+Shamban has developed the ZurconR LCupR, a highly effective and innovative rod sealing component. escription ZurconR LCupR is a single acting polyurethane rod seal with a unique design offering a hydrodynamic backpumping ability over the complete working pressure range. The pressureindependent, hydrodynamic sealing ability of this new sealing element requires no lubrication reservoir in the sealing area and ensures a constant and controlled pressure distribution over a wide pressure range. Additionally, the seal s dynamic sealing edge has a highly effective frictionreducing microstructure. This structure creates a constant lubrication film to prevent dry running, thus enabling an increased service life. The advantages of the new to the following improved properties: dimensions according to ISO 5597 Part 2 Interchangeable with existing UCup grooves Installation into closed grooves Wear and extrusion resistant highperformance polyurethane Patent No. E C1 ZurconR LCupR can be used in all applications in which previously a conventional UCup was applied, such as: ZurconR LCupR is a trade name.

Another preferred solution for tandem rod sealing systems is the combination with the TurconR StepsealR K as primary seal and LCupR as secondary seal, in conjunction with a double acting scraper.

61 ZurconR LCupR Busak+Shamban s experience in the production of hydrodynamic backpumping seals such as TurconR StepsealR K, and the use of Finite Element Analysis (FEA) and other laboratory tests have led to the development of ZurconR LCupR. The main objective in the development of this seal was the ability to achieve an optimum pressure distribution over the complete pressure range. The pressure distribution curve under the sealing lip needs to have a steep gradient on the highpressure side and a shallow gradient on the rear of the seal. The operating principles and function of ZurconR LCupR is similar to the wellknown TurconR StepsealR K. uring short stroke oscillation, oil is retained in the microstructures. This result would be unlikely with smooth sealing surfaces where full contact with the rod causes the oil to be pressed out N LCupR Friction In Figure 29 the friction values of a conventional UCup and of ZurconR LCupR are being compared. A high increase in friction of the UCup is clearly shown between approximately 5 and 15 MPa. This is due to the UCup being totally pressed on the rod surface at increased pressure, causing elimination of the oil reservoir and dry running of the UCup. LCupR shows only a low increase in In comparison, the friction which is due to the smaller contact area and better tribological behaviour. The result is a very low friction heat generation. UCup 2 UCup Friction force Method of Operation m/s 0.4 Speed Figure 30 Friction dependent on speed Friction Heat The effect described above can be made visible by simply measuring the temperature. Figure 31 shows the increase in temperature on the rod surface caused by friction, measured at a pressure of 40 MPa after cycles. This explains the prolonged service life of LCupR N HLP 46 Ø45 mm C UCup Friction force 900 LCupR MPa 20 Pressure Figure 29 LCupR Nutring 60 Friction dependent on pressure The surface microstructure reduces the effective contact area to the rod and therefore the breakout and dynamic friction are reduced compared to seals with smooth sealing surfaces. The hollow spaces between the peaks of the seal and the rod are filled with oil even during long periods without operation. When starting the movement after this period, a lubrication film is still present. This reduction of a large surface contact area into many small contact points also prevents excessive breakout friction and stickslip.

67 UCup RU0 UCup RU0 escription Technical ata Today UCups are used primarily as seals for piston rods in hydraulic cylinders. UCups in polyurethane are proven elements, due to their good mechanical properties, for standard cylinder construction, particularly for mobile hydraulics under rough operating conditions. Operating pressure: Max. 40 MPa Speed: Up to m/s Temperature: Use in mineral oils: 30 C to + 80 C The UCup is a single lip seal. Media: Mineral oilbased hydraulic fluids. Type RU0 The UCup type RU0 is installed as a singleacting singlelip compact seal. The seal is installed with a simple snap fitting and seals statically on the outside diameter via a fixed seat. It has an asymmetric seal lip profile with shortened inner lip. This form can absorb deflections in the piston rod more easily than, e.g. UCup Form RU2 with its more rigid lip geometry. In pressurefree state, it exhibits lower frictional forces than doublelipped UCups. Important Note: The above data are maximum values and cannot be used at the same time. e.g. the maximum operating speed depends on material type, pressure, temperature and gap value. Seal clearance Guide values for the radial clearance between rod and gland in relation to the operating pressure and rod diameter can be found in Table XX. Table XX Clearance Operating max. Pressure MP MPa p Figure 35 UCup, type RU0 Method of Operation The sealing effect of the UCup comes from the intrinsic preload of the seal body and from the compression of the seal lips during installation. In operating condition, the radial mechanical contact forces are superimposed by the system pressure. At low stroke speeds, UCups can tend to have a stickslip effect due to an inadequate lubrication film formation in the seal clearance and to their material properties. This behaviour corresponds to the Stribeck curve described in the relevant literature. Advantages Good pressureadapted sealing effect Unaffected by high loads and deflections of the piston rod Radial Clearance S max. dn <60 mm dn >60 mm The values for S max given in this table apply to all types for the lowpressure side of the UCup. They are designed for an operating temperature of 60_C. Material The thermoplastic polyurethane material used for UCups has a high abrasion resistance, a low compression set and exhibits a high resistance to clearance extrusion. WUAQ3 WU9L3 UAT60 turquoise color blue color red color esign and Installation Instructions The different forms have different grooves, see Tables XXI and XXII. UCups are used together with singleacting scrapers. Good resistance to clearance extrusion Simple installation Lower friction in the low pressure range compared with doublelipped versions. 79

80 UCup RU1 UCup RU1 escription Technical ata Today UCups are used primarily as seals for piston rods in hydraulic cylinders. UCups in polyurethane are proven elements, due to their good mechanical properties, for standard cylinder construction, particularly for mobile hydraulics under rough operating conditions. Operating pressure: Max. 40 MPa Speed: Up to m/s Temperature: Use in mineral oils: 30 C to + 80 C The UCup RU1 is a single lip seal in a compact design. Media: Mineral oilbased hydraulic fluids. Type RU1 The compact UCup type RU1 is designed for small grooves. It is thus particularly suitable for use in spacesaving designs. The compact form provides a high sealing effect even with low system pressures. The UCup has one sealing lip in the dynamic sealing zone. The compact form provides an improvement in the leakage behaviour at low system pressures. Important Note: The above data are maximum values and cannot be used at the same time. e.g. the maximum operating speed depends on material type, pressure, temperature and gap value. Material The thermoplastic polyurethane material used for UCups has a high abrasion resistance, a low compression set and exhibits a high resistance to clearance extrusion. WUAQ3 WU9L3 UAT60 turquoise color blue color red color Seal clearance Guide values for the radial clearance between rod and gland in relation to the operating pressure and rod diameter can be found in Table XX page 77. P esign and Installation Instructions The different forms have different grooves, see Table XXII. UCups are used together with singleacting scrapers. Figure 37 UCup, type RU1 Method of Operation The sealing effect of the UCup comes from the intrinsic preload of the seal body and from the compression of the seal lips during installation. In operating condition, the radial mechanical contact forces are superimposed by the system pressure. At low stroke speeds, UCups can tend to have a stickslip effect due to an inadequate lubrication film formation in the seal clearance and to their material properties. This behaviour corresponds to the Stribeck curve described in the relevant literature. Advantages Good sealing effect at high and low pressures Good abrasion resistance, wearresistant Unaffected by sudden loads Suitable for small grooves Simple installation. 93

UCups in polyurethane are proven elements, due to their good mechanical properties, for standard cylinder construction, particularly for mobile hydraulics under rough operating conditions. Good sealing effect even in pressurefree state Type RU3 Low stickslip effect The UCup type RU3 is used as a rod seal for heavyduty conditions in mobile and industrial hydraulics. It is installed with a fixed seat at its outer diameter. The rear dynamic sealing lip improves the leakage behaviour and, at the same time, prevents the entry of contaminants from the atmosphere side. Compared with the type RU2, the shorter inner lip is more flexible and can adapt better to the operating conditions and deflections of the piston rod. A lubricant trap forms between the sealing lips. This counters the stickslip tendency and prevents dry running. At the same time the good lubrication behaviour reduces wear. Good abrasion resistance, wearresistant Good lubricant film formation in the seal clearance Compensates deflections of the piston rod Entry of dirt and air into the system is more or less ruled out Unaffected by sudden loads and high pressures Simple installation.

109 UCup RU3B Type RU3B Material The UCup type RU3B is used as a rod seal for heavyduty conditions in mobile and industrial hydraulics. It is installed with a fixed seat at its outer diameter. The rear dynamic sealing lip improves the leakage behaviour and, at the same time, prevents the entry of contaminants from the atmosphere side. Compared with the type RU2, the shorter inner lip is more flexible and can adapt better to the operating conditions and deflections of the piston rod. The thermoplastic polyurethane material used for UCups has a high abrasion resistance, a low compression set and exhibits a high resistance to clearance extrusion. UCup RU3B has integrated up Ring to prevent the seal material from extrusion at high temperatures and high peak pressures. Material set code: UCup material: WU9L3 blue color up ring material: Polyamid PA WUR0L A lubricant trap forms between the sealing lips. This counters the stickslip tendency and prevents dry running. At the same time the good lubrication behaviour reduces wear. p Figure 45 UCup, type RU3B Advantages Good sealing effect even in pressurefree state Good abrasion resistance, wearresistant Good lubricant film formation in the seal clearance Compensates deflections of the piston rod Low stickslip effect Entry of dirt and air into the system is more or less ruled out Unaffected by sudden loads and high pressures Good extrusion resistance Larger sealing gaps (approx. 50% larger than table XX values) Suitable for high pressure peaks 125

113 UCup RU6 UCup RU6 escription Application Examples additional to the machined seals StepsealR K and Rimseal S S S S for housings due to ISO 7425/2 (rubber energised plastic seals) the UCup type RU6 has been developped as an injection molded seal of polyurethane material to fit in the same ISO housings. The integrated NBR ORing (only available for series RU62 RU64) improves the performance at low pressure and low temperature applications. Polyurethan (ZurconR Z04) is a proved material for Ucups due to their good mechanical properties. Type RU6 The UCup type RU6 can be installed as a single seal for low to medium duty applications; for sealing systems, the UCup RU6 shall be installed mainly as a secondary seal together with the TurconR StepsealR K as primary seals. General hydraulic cylinders Injection molding machines Lift trucks Agricultural machines Technical ata Operating pressure: Max. 25 MPa (as single element) Speed: Up to m/s Temperature: Use in mineral oils: 30 C to + 80 C Media: Mineral oilbased hydraulic fluids. Important Note: The above data are maximum values and cannot be used at the same time. e.g. the maximum operating speed depends on material type, pressure, temperature and gap value. Clearance P Operating Pressure MPa max. Radial Clearance S max The values for S max given in this table apply to all types for the lowpressure side of the UCup. They are designed for an operating temperature of 60_C.(for harsh conditions and high side loads the gap must be reduced by 50%) Figure 47 UCup, type RU6 Method of Operation The sealing effect of the UCup RU6 comes from the intrinsive preload of the seal body and from the compression of the seal lip and the ORing during installation. In operation conditions, the radial contact forces are superimposed by the system pressure. Material The thermoplastic polyurethane material ZurconR Z04 has a high abrasion resistance, a low compression set and exhibits a high resistance to clearance extrusion. ue to the special design and the integrated ORing the RU6 UCups have an excellent sealing behavior with and without pressure activation. The short sealing lip gives better friction values compared to common UCups.

118 TurconR VarisealR M2 TurconR VarisealR M2 Advantages escription TurconR VarisealR M2 is a singleacting seal The consisting of a Ushaped seal jacket and a Vshaped corrosion resistant spring. Resistant to most fluids and chemicals The characteristic of the VarisealR M2 is the newly developed asymmetric seal profile, where the dynamic lip has an optimized short and heavy profile, offering reduced friction and long service life. Stickslipfree operating for precise control Low coefficients of friction High abrasion resistance and dimensional stability Can handle rapid changes in temperature No contamination in contact with foodstuffs, pharmaceutical and medicinal fluids S TurconR Seal ring High temperature range Vshaped spring Unlimited shelf life. Sterilisable Application Examples TurconR VarisealR M2 is the recommended sealing element for all applications requiring stick slip free operation as well as chemical resistance against almost all media such as: Figure 49 TurconR VarisealR M2 At low and zero pressure, the metal spring provides the primary sealing force. As the system pressure increases, the main sealing force is achieved by the system pressure and ensures a tight seal from zero to high pressure. The possibility of matching suitable materials for the seal and the spring allows use in a wide range of applications going beyond the field of hydraulics, e.g. in the chemical, pharmaceutical and foodstuff industry. The VarisealR M2 can be sterilized and is available in a special HiClean version where the spring cavity is filled with a Silicone gel preventing contaminants from being entrapped in the seal. This design also works well in applications involving mud, slurries or adhersives to keep grit from packing into the seal cavity and inhibiting the spring action. For applications with highly viscous media, please contact our engineering department. VarisealR M2 seals can be installed in grooves to MIL G 5514F and ISO The seal can only be installed to a limited extent in closed grooves. Installation instructions, see fig. 14 page 15.

123 TurconR Glyd RingR TurconR Glyd RingR escription Successfully used for decades, the TuconR Glyd RingR is a very effective and reliable low frictional seal. It is particularly suitable as a rod seal in both high and low pressure systems. The double acting TuconR Glyd RingR is a combination of a Turcon based slipper seal and an energising ORing. It is produced with an interference fit which together with the squeeze of the ORing ensures a good sealing effect even at low pressure. At higher system pressures, the ORing is energised by the fluid, pushing the TurconR Glyd RingR against the sealing face with increased force. Notches are standard on the following series and diameters RG 41 for bore dia. > 30mm RG 43 for bore dia. > 20mm RG 45 for bore dia. > 40mm Advantages No stickslip effect when starting for smooth operation Minimum static and dynamic friction coefficient for a minimum energy loss and operating temperature Suitable for non lubricating fluids depending on seal material for optimum design flexibility High wear resistance ensures long service life Installation grooves acc. to ISO 7425/2 No adhesive effect to the mating surface during long period of inactivity or storage Suitable for most hydraulic fluids in relation with most modern hardware materials and surface finish depending on material selected. Suitable for new environmentally safe hydraulic fluids Available for all rod diameters up to mm. Figure 51 TurconR Glyd RingR The geometry of the TuconR Glyd RingR ensures a good static sealing and allows the lubricating hydrodynamic oil film to be build under the seal in reciprocating applications. Notches To assure that a rapid energising of the seal takes place at sudden changes of pressure and direction of motion, radial notches are machined on both sides of the seal. Pressure Applications examples Over several decades the TurconR Glyd RingR has been successfully implemented in a lot of applications as double acting seals of hydraulic components such as: S S S S S Injection moulding machines Machine tools Presses Handling machinery Valves for hydraulic & pneumatic circuits.

131 TurconR Glyd RingR T TurconR Glyd RingR T escription TurconR Glyd RingR T is a further technical development of the TurconR Glyd RingR seal which has been successfully used for decades. It is fully interchangeable with the earlier Glyd RingR seals in all new applications. Glyd RingR T meets all the market demands for a functionspecific seal solution, observing economic and ecological aspects. The benefits of the patented seal concept are provided by the innovative functional principle of the trapezoidal profile crosssection. PatentNo. P p1 Figure 54 Both lateral profile flanks are inclined so that the seal profile tapers towards the seal surface. The profile can thus retain the robust and compact form typical of piston seals without losing any of the flexibility required to achieve a pressurerelated maximum compression (Figure 54). The edge angle created by the special Glyd RingR T crosssectional form permits an additional degree of freedom and enables a slight tilting movement of the seal. The maximum compression is thus always shifted towards the area of the seal edge directly exposed to the pressure. On the lowpressure edge of the seal, on the other hand, the Glyd RingR T exhibits only zones with neutral strains without compressive or shearing loads, thus effectively reducing the danger of gap extrusion. The resulting benefits for the user can be seen in the following list. p2 TurconR Glyd RingR T Application Examples Advantages RingR are still The benefits offered to date by the Glyd retained in full, and are now complemented by a number of further important advantages: The TurconR Glyd RingR T is the recommended sealing element for double acting inside sealing seal for hydraulic components such as: Very good static leaktightness S Injection moulding machines S Machine tools S Presses S Handling machinery S Agriculture S Valves. It is particularly recommended for heavy duty and large diameter applications. Increased clearance possible (approx. +50%), depending on the operating conditions Low friction, no stickslip effect Simple groove design Installation grooves to ISO 7425/2 Available for all rod diameters up to mm. 153

138 R R TURCON OUBLE ELTA ouble Acting Rubber Energised Plastic Faced Seal For ORing s Material TurconR 161

139 TurconR ouble eltar TurconR ouble eltar escription TurconR eltar ouble is an rubber energised plastic faced seal. The seal is designed to expand and improve the service parameters of ORings and is installed in existing ORing grooves. For diameters from 8 mm notches on both sides are optional. These ensure direct pressurizing of the seal under all operating conditions. ouble eltar combines the flexibility and response of ORings with the wear and friction characteristics of the Turcon materials in dynamic applications. The figures below shows the cross section of the ouble eltar. Pressure The double acting performance of the seal follows from the symmetrical cross section which allow the seal to respond to pressure in both directions. Initial contact pressure is provided by radial compression of the ORing. When the system pressure is increased the ORing transforms this into additional contact pressure, the contact pressure of the seal is thereby automatically adjusted so sealing is ensured under all service conditions. Notches Figure 57 TurconR ouble eltar with notches Advantages Compact groove dimensions and simple installation Low friction without stickslip Resistance against wear and extrusion seals available for all diameters from 2 to mm Standard cross sections cover AS 568A and important metric ORings, other cross sections available on request. Fits also groove dimensions per MILG5514F Pressure Figure 56 TurconR ouble eltar without and with pressure Notches TurconR ouble eltar is as standard supplied without radial notches, as the thin radial section of the seal gives good response to pressure variations. 163

140 TurconR ouble eltar Application Examples The TurconR ouble eltar is preferably used as a double acting seal for hydraulic and pneumatic equipment in sectors such as: S Machine tools S Handling devices S Manipulators S Valves S Chemical process equipments It is particular recommended for light duty and small diameter applications. Technical ata Operating conditions Pressure: Up to 35 MPa Velocity: Up to 15 m/s Temperature: 45_C to +200_C (according to ORing material) Media: Mineral oil, Nonflammable fluids, Environmentally safe fluids and others according to ORing material. Important Note: The above data are maximum values and cannot be used at the same time. e.g. the maximum operating speed depends on material type, pressure, temperature and gap value. 164
