Hydraulic Wear Rings

Slydring® for hydraulic cylinders

Slydring® is the Trelleborg Sealing Solutions proprietary design of hydraulic wear ring or guide ring. The function of a hydraulic wear ring is to guide the piston and piston rod of a hydraulic cylinder, absorbing transverse forces. At the same time, it prevents metal-to-metal contact, optimizing the performance of the sealing system.

Technical Resources

 

HiMod® Slydring® | Hydraulic Wear Rings | Trelleborg

HiMod® Slydring® prevents metal-to-metal contact between piston / rod and bore / gland, absorbing transverse loads. The modified polymeric material provides an economical solution for applications with medium transverse loads, while giving good wear and compression properties. The Slydring® is easily installed by snap-fitting and offers good dryrunning and wiping performance. Higher static loads are permissible.

Features: Helix, Oscillating and Reciprocating

Ø – Range Pressure Range Temp. range Velocity
8 – 915 mm 50 MPa -40°C +135°C 1 m/s
0.315 – 36 in 7200 psi -40°F +275°F 3 ft/s

Orkot® Slydring® | Hydraulic Wear Rings | Trelleborg

Orkot® Slydring® prevents metal-to-metal contact between piston / rod and bore / gland, absorbing high transverse loads. Orkot® is a resinimpregnated, fine weave fabric material with added lubricants. It is capable of withstanding high side loads, damping vibrations and embedded foreign particles. Higher static loads are permissible. Special materials are available with operating temperatures up to +250 °C / +482 °F.

Features: Helix, Oscillating and Reciprocating

Ø – Range Pressure Range Temp. range Velocity
8 – 1,500 mm 100 MPa -40°C +120°C 1 m/s
0.315 – 59 in 14,500 psi -40°F +250°F 3 ft/s

Turcite® Slydring® | Hydraulic Wear Rings | Trelleborg

Turcite® Slydring® prevents metal-to-metal contact between piston / rod and bore / gland, absorbing transverse loads. Turcite® material gives good load capacity with low friction and stick-slip-free operation. The Slydring® protects critical sealing lips from contamination and dieseling effects. Cost-effective, it allows designers freedom in hardware material selection. Higher static loads are permissible.

Features: Helix, Oscillating and Reciprocating

Ø – Range Pressure Range Temp. range Velocity
8 – 4,200 mm 15 MPa -60°C +200°C 15 m/s
0.315 – 165 in 2200 psi -75°F +390°F 50 ft/s
