piston seal
Description
PSH + RR is a piston seal very similar to PSA but with a back-up ring of thermo plastic resin and a guide ring of glass fiber reinforced acetalresin.
This allows to avoid slot extrusion, and can compensate for any eccentricity
Material
Sealing: Polyurethane (PU)
Guide ring: Glass fiber reinforced acetal resin
Support ring: Thermoplastic resin
Technical data
Pressure: <400bar at 60 ° C
Speed: <0.5 m / s
Temperature: -35 ° C to + 100 ° C with peak of 110 ° C
Mounting
It is important that the piston does not have burrs or other sharp edges which might damage the seal during installation.
The inlet of the cylinder is made for ease of pushing the piston in.
We recommend that the piston is lubricated for easier assembly.
