19 1/2 X 20 Back-up SOLID PTFE

Used primarily as an anti-extrusion device for u-seals, these back-up rings combine high performance with very low friction. “ST” suffix designates a split ring.

PTFE Material | 2 in Nominal Inner Diameter | Backup Ring

Features

• High strength and abrasion resistance
• Wide temperature range
• Chemical resistance
• Low friction
• Easy installation

Wear rings provide a hard-wearing surface that protects the cylinder walls and the piston rod from scoring and abrasion. By maintaining alignment and reducing side loads, these rings facilitate smoother piston movement and lower friction levels.

92A Durometer | Urethane Material | 2 1/2 in Nominal Inner Diameter | Buffer Seal

5 1/16 in Nominal Inner Diameter | Piston T-Seal

5 1/16 in Nominal Inner Diameter | Piston T-Seal

Style DRTU-BHT rod seals are molded in Freudenberg® AU 30000 urethane. These seals are specifically designed, with a second lip on their inside diameter and engineered to attain maximum life and reliability in dynamic rod sealing., This feature results in reduced leakage, less friction, increased stability, and prevents air and contaminants from, entering the cylinder. This high tear-resistant urethane demonstrates stability throughout a wide range of temperatures., In addition, this material is well suited to mineral and biodegradable hydraulic fluids as well as being resistant to, hydrolysis.

Features

• General purpose rod seal
• Robust design
• Excellent wear resistance
• Increase seal stability
• Performs well over wide temperature range and is extremely effective in low temperatures
• Primary lip protection
• Easy to install
