4 Choice of Slydring R The function of Slydring R is to guide the piston and piston rod of a hydraulic cylinder and to absorb the transverse forces which occur. At the same time, metallic contact between the sliding parts of the cylinder, e.g. piston and cylinder barrel or rod and cylinder head, must be prevented. Nonmetallic guide rings offer major benefits compared with the traditional metallic guides: Cost efficient production High load bearing capacity Eliminates local stress concentrations Wearresistant, long service lives Metal/plastic pairing eliminates fretting and seizure Favourable friction behaviour amping of mechanical vibrations Good wiping effect, embedding of foreign particles possible Protection of the seal against dieseling Free choice of material of the metal components as guiding properties are no longer required Eliminates hydrodynamic pressure problems in the guide system Simple closed groove, easy installation Low service costs In principle, piston Slydring R and rod Slydring R are interchangeable if the difference in size is taken into consideration, e.g. piston ring, diameter 100 x 2.5 mm thick can be used as a piston rod Slydring R diameter 95 x 2.5 mm thick. epending on the material and dimensions of the Slydring R, the thickness tolerance is in the range of +0 to 0.08 mm. Please do not hesitate to contact our Technical epartment for further information on specific applications and special technical questions. Materials In view of the different specific demands made on piston and rod guides, various Slydring R materials are available: Highly wearresistant, low friction, specially modified Turcite R materials for low to medium duty with limited radial forces HiMod R materials with frictionreducing fillers for medium to heavy duty Luytex R fabric composite materials for heavy duty and high radial forces In order to choose the most suitable Slydring R,itisfirst necessary to know all the required functional parameters. Table I can be used to make an initial preselection of the Slydring R and the materials to meet the demands of the application. Before the final choice of Slydring R and material is made, the details and information must be checked in the relevant data sheets of Slydring R materials. 4

Angle cut, standard design Straight cut, special design Step cut, special design Figure 1 Type of cut esigntype Slydring R have a rectangular crosssection with rounded or chamfered edges, thus preventing impermissible edge forces in the corner radii of the grooves. The chamfers also serve to facilitate installation, e.g. when inserting into the cylindrical tube or guide bush. Slydring R are supplied ready to fit with the gap necessary (dimension Z) for their function. The ring ends are finished as standard with an angle cut. For further details, please refer to Table II. Slydring R are depending on material supplied as split rings and/or as strip material. Strip material is available in rolls or precut to size as listed in Table II.

7 esign Instructions Choice of Slydring R An initial selection can be made for various application, see Table I. The values for the load on the Slydring R are valid for a load distribution as illustrated in Figure 2. The flexibility of the materials ensures a relatively constant specific load, irrespective of the size of the radial forces F, as with increasing radial loading, the guide surface subjected to the load increases also. The radial forces which occur can vary within wide ranges and cannot always be calculated exactly in advance. For such cases, a safety factor of at least 2 is recommended when calculating (see calculation example). F T T imensioning of Slydring R The load, and thus the resulting elastic deformation, is critical for the design of the Slydring R. The Slydring R clearance resulting from the dimensional tolerance, deformation and wear must always be smaller than the smallest gap to be sealed in the system. On request, we are willing to carry out dimensioning calculations for specific applications. A rough estimate of the number and width of Slydring R required can be calculated using the following formula: Fx f Slydring R width T total = d x Pr where: F = Maximum radial load [N] f = Safety factor d N = Rod diameter [mm] Pr = Permissible dynamic load [N/mm 2 ] Example: d N = 60 mm F = N t = 70 d C f = 2 Slydring R material Luytex R C 380 Pr per. 100 N/mm 2 Total = x 2 60 x 100 N = 13.3 mm From Table V, a groove with a width of 15 mm or 2 grooves with widths of 9.7 mm are selected. The installation of two strips is recommended as this gives a wider guide length. Selected: 2 strips Series GR69 with a groove width L 2 =9.7mm With this choice, the safety factor increases to 2.9. Figure 2 Load distribution The large effective bearing area of nonmetallic Slydring R gives low maximum contact pressure. 7

Figure 3 Figure 4 Z Z W T N 2 Piston guide W T N d2 d Rod guide To further improve the operational safety, particularly under high loads, the installation of a 3rd strip made of material Turcite R T47 is recommended. It is installed on the oil side and serves eg as an internal scraper seal where contaminated media may be involved. Calculation of the Linear Length The linear length of Turcite R and Luytex R Slydring R are calculated such that a gap Z is created at the ends of the strip after installation (see Figure 3 and 4). This is required for the following reasons: Compensation of the linear expansion of the strips due to the effects of temperature Avoidance of intermediate pressures and entrained pressures. When ordering strips offtheroll for manufacturing of Slydring R in your own works, the length of the strip can be calculated using the following formulae: Piston Slydring R : L= cx( N W) k [mm] Rod Slydring R : L= cx(d N + W) k [mm] N d N = Bore diameter [mm] = Rod diameter [mm] W = Ring thickness [mm] c = k = 3.11 material factor, valid for all materials Temperature constant: 0.8 for all materials. 1.8 only for Turcite R materials for applications > 120 C.

9 Turcite R Slydring R for Piston and Rod escription Turcite R Slydring R areusedaspistonandrodguidesdue to their outstanding friction behaviour, stickslip free running and good resistance to high temperatures and chemicals. Slydring R are available as offtheroll materials for cutting to length in the users works as listed in Table V. Sections cut to size ready for installation is available for rod and piston diameters according to Table II. Slydring R have a geometrically rectangular crosssection and are chamfered at the edges for easy installation into the grooves. Teardrop structure Slydring R up to and including 3 mm radial thickness in Turcite R materials are as standard supplied with teardrop structure on the sliding surfaces. This structure comprises small lubricant pockets on the surface which improve the initial lubrication and promote the formation of a lubricant film. They also help to protect the seal system through their ability to embed any foreign particles. In order to be able to use the strip material for both piston and piston rod guides, the rings have this same teardrop structure on both sides. Figure 8 Teardrop structure for Turcite R Slydring R Slydring R can also be delivered without teardrop structure. In this case, this must be indicated in the Order No. (see esign Code for cut/type in Table III). Advantages Outstanding lubrication conditions further improved by the Teardrop structure No stickslip effect when starting for smooth operation even at very low speeds Minimum static and dynamic friction coefficient for low operating temperature and energy loss Suitable for non lubricating fluids depending on Turcite R material for optimum design flexibility High wear resistance ensures long service life Installation grooves according to ISO Suitable for most hydraulic fluids in relation with the majority of modern hardware materials and surface finish depending on material selected. Suitable for new environmentally safe hydraulic fluids The embedding of foreign particles is enhanced Good damping effect, absorbs vibrations Figure 7 Turcite R Slydring R with teardrop structure 9

10 Application Examples The Turcite R Slydring R is successfully applied in demanding applications as a standard guiding element for hydraulic operated pistons, plus for piston rods with special requirements, in: S Machine tools S Injection moulding machines S Press brakes S Presses S Robotics & Handling machinery S Automation S Positioning cylinders S Servo hydraulics S Piston accumulators S Shock absorber S Valves for hydraulic & pneumatic circuits S Agriculture S Chemical and Process Industry Technical ata The Turcite R Slydring R with angle cut is recommended for reciprocating movements Speed: Temperature: Media: Clearance: up to 15m/s 60 C to +150 C (200 C) Mineral Oil based Hydraulic fluids, barely flammable hydraulic fluids, environmentally safe hydraulic fluids (biological degradable oils), water, air and others. epending on the Turcite R material compatibility. The maximum permissible radial clearance smax is depending on the actual sealing system. ynamic load F: Max. 15 N/mm 2 at 25 C (Values for size and quantity calculation) With the Turcite materials it must be taken into account that the permissible surface pressure decreases with increasing temperatures. The load bearing ability for dynamic applications in practice is dependent primarily on the operating temperature. This should therefore generally not exceed 150 C. 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. Materials Various Turcite R materials are recommended for piston and piston rod guides as shown in Table I.
