Rod Seal XSRS09
Function:
Rod seals are designed to seal the pressurized hydraulic fluid against the atmosphere, preventing leakage and pollution of the environment.
Features:- Asymmetrical, single acting rod seal, designed with interference of the O-Ring on the OD and slight interference of the PTFE glide ring on the ID.
- Excellent sealing performance in low and high speeds.
- Suitable for positioning functions.
- Negligible tendency to “stick-slip” effect, good sliding properties.
- Low break-away load after long standstills.
- Excellent gap extrusion resistance due to the free space on the trailing side.
