7 Slydring R -WearRing 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. Non-metallic guide rings offer major benefits compared with the traditional metallic guides: - Cost efficient production - High load bearing capacity - Eliminates local stress concentrations - Wear-resistant, 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 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 wear-resistant, low friction, specially modified Turcite R materials for low to medium duty with limited radial forces - HiMod R materials with friction-reducing 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 Busak+ Shamban Edition ecember 2004

10 Slydring R -WearRing esign Instructions Selection of Slydring R An initial choice can be made for various application by checking the Selection Criteria for Slydring R in Turcite R, Zurcon R,HiMod R or Luytex R, see Table I and the pages 10, 11, 20, 21 and 43. 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 imensioning of Slydring R The radial bearing pressure and the resulting elastic deflection are important parameters in the design of the Slydring R. The radial offset resulting from the dimensional tolerances, deflection and wear should always be less than the smallest gap to be sealed by 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 = Radial Slydring R pressure [N/mm 2 ] Example: d N = 60 mm F = N t = 40 d C f = 2 N Slydring R material Luytex R C 380 Pr per. 100 N/mm 2 T total = x 2 60 x 100 = 13.3 mm T From Table IV, 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 Figure 2 Load distribution The large effective bearing area of non-metallic Slydring R gives low maximum contact pressure.

11 Slydring R -WearRing The standard installation arrangement for pistons and rods is shown in Figures 3 and 4. 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. 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 off-the-roll 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. 2.0 only for Turcite R materials for applications > 120 C.

12 Turcite R Slydring R -WearRing Turcite R Slydring R for Piston and Rod escription Turcite R Slydring R are used as piston and rod guides due to their outstanding friction behaviour, stick-slip free running and good resistance to high temperatures and chemicals. Slydring R are available as off-the-roll 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 cross-section 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 stick-slip 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 Edition ecember 2004 Busak+ Shamban 9

13 Turcite R Slydring R -WearRing 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. Radial Slydring R pressure Pr: Max. 15 N/mm 2 at 25 C Max. 12 N/mm 2 at 80 C Max. 8 N/mm 2 at 120 C When calculating the width of Turcite R Slydring R it is recommended to use a safety factor f=2 (see page 7). With the Turcite R 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 stated limits for pressure and speed are maximum values individually. Friction heat generated by the combination of pressure and speed may cause local heat built-up. Care should be taken not to apply high values for pressure and speed at the same time.

46 Luytex R Slydring R -WearRing Luytex R Slydring R for Piston and Rod escription Luytex R Slydring R of fabric reinforced composite materials is used in hydraulic cylinders exposed to high loads that can occur e.g. in mobile hydraulics and presses. The high compressive strength, good sliding behaviour and the exceptional wear resistant properties ensure a long service life. Slydring R of Luytex R fabric composite materials is produced as standard from tubular material. It is manufactured with a angle cut and already has the necessary gap Z. For large diameters > 300 mm, sections or segments can be produced from Luytex R C320, C380 strip material. This offers economical solutions for non-standard diameters or when quantities are limited. Strip material is coiled to a diameter of 200 to 300 mm and can be ordered either: - cut and finished to the required length ( see page 6) - coils at full lengths of 2 m or 3 m (see next page) Strip material requires more care in fitting, in particular if the diameter is below 200 to 300 mm. Advantages - imensionally stable and vibration absorbing - Even distribution of high radial forces - Good sliding and dry running properties - High wear resistance - Good wiping effect - Long service life. Application Examples Luytex R Slydring is widely used as a bearing element for heavy duty hydraulic equipment: S Hydraulic actuators S Mobile hydraulics S Excavators S Construction equipment S Forrestry machinery S Mining S Steel mills S Presses S Water locks S Marine engineering Technical ata Velocity: Up to 1 m/s, with reciprocating movements Temperature: - 60 C to C Pr under dynamic conditions (C380, C320, C932): max. 100 N/mm 2 at 25 C max. 50 N/mm 2 >60 C Ultimate compressive strength (C380, C320): max. > 300 N/ mm 2 (C932): max. 260 N/mm 2 When calculating the width of Luytex R Slydring R it is recommended to use a safety factor f=2 (see page 7). Important Note: The above stated limits for pressure and speed are maximum values individually. Friction heat generated by the combination of pressure and speed may cause local heat built-up. Care should be taken not to apply high values for pressure and speed at the same time. Materials Luytex R C320 Luytex R C320 is a fabric composite material made of a thermosetting polymer, reinforced by a fine plastic mesh and lubricant additives impregnated throughout the material. It has a very high resistance to wear, good dryrunning properties and dampens vibrations. Colour: dark gray. Luytex R C380 Luytex C380 is the standard material, this turquoise coloured composite is a further development of the proven C320. It is most versatile; suitable for all commonly used hydraulic fluids such as mineral or synthetic oils, as well as water based fluids. It is an excellent electrical insulator and features enhanced sliding properties in various media. Luytex R C932 A composite of phenolic resin impregnated into a fine cotton fabric. The material stiffness is higher than C380 / C320. The use in water based fluids is not recommended. Colour: yellow-brown. Edition ecember 2004 Busak+ Shamban 43

The larger face area of these rings (Series GP 99 from Table IV) embeds the contaminant particles when present inthesystemandkeepsthemawayfromtheactualguides and seals (Figure 15).

For Slydring R to other standards, e.g French standard NF E , please contact us. Radial clearance S1 The minimum radial gap is to be calculated taking into account; - the fitting tolerances of the hardware - the tolerance on the ring thickness - an allowance for wear - in case of high radial loads an allowance for elastic deformation - a safety margin to avoid metal-to-metal contact The gaps S1 can be chosen larger than near to the seal (attention: take care of gap dimension for the seal) thus allowing slight tilting of the piston, still without metal-tometal contact. It also allows foreign particles to be wiped away by the Slydring R rather than being squeezed between the metal components. The slot Z allows fluid to pass across the ring thus preventing fluid pressure build-up which might cause extrusion of the guide ring. To ensure the ring cannot escape out of the groove it is recommended to observe following radial gap sizes as maximum: mm for GP43 ( 1.55 mm thickness) mm for GP65 to GP75 ( 2.50 mm thickness) mm for GP98 and GP98X ( 4.00 mm thickness) Table XLIII Parameter Surface Roughness Mating Surface µm Luytex R Materials Surface µm R max < 16.0 R zin < 10.0 R a < 2.5 Edition ecember 2004 Busak+ Shamban 45
