Piston Seal XSPS81B
Function:
Piston seals are designed to seal the pressurized hydraulic fluid against
the atmosphere or between two pressurized spaces.
Eigenschaften:
- Asymmetrical, single acting piston seal, designed with interference
of the preload element on the ID and slight interference of the PTFE
glide ring on the OD.
- High pressure force because of a machined rubber preload element.
- Less relative movement of the rubber part compared to an O-Ring
giving the seal a higher wear resistance. - 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.
- Can be used in grooves where no O-Ring is possible.
