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 O-Ring
on the ID and slight interference of the glide ring on the OD.
- Glide ring commonly made in hard grade Polyurethane (PU-D57).
- 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.
Application
Reciprocating pistons in hydraulic cylinders, plungers.
Dynamic seals in hydraulic systems.
Max. pressure 250 bar, max. speed 1 m/s (PU-D57)
Max. pressure 400 bar, max. speed 10 m/s (PTFE Materials)
Installation
Snap-in installation.
Attention: PTFE glide rings needs calibration after installation!
