Description
Function
Piston seals are designed to seal the pressurized hydraulic fluid against the atmosphere or
between two pressurized spaces.
Features
- Symmetrical, double 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.
Application
Reciprocating pistons in hydraulic cylinders, plungers in heavy-duty applications.
Max. pressure 400 bar, max. speed 10 m/s.
Installation
Snap-in installation.
Attention: PTFE glide rings needs calibration after installation!
