Operating Conditions 

Pressure Up to 50 MPa
Speed Up to 15 m/s with linear movements, frequency up to 15 Hz
Temperature -45 °C to +200 °C. Depending on seal and O-Ring material
Media Mineral oil based hydraulic fluids, flame retardant hydraulic fluids, environmentally friendly hydraulic fluids (bio-oils), phosphate ester, water and others, depending on the seal and O-Ring material.
Clearance The maximum permissible radial clearance Smax is shown in Installation Dimensions, as a function of the operating pressure and functional diameter.

Important Note : The above data are maximum values and cannot be used at the same time, e.g. the maximum operating speed depends on material type, pressure, temperature and gap value. Temperature range also depends on media.



Recommended Materials 

The following material combinations have proven effective for hydraulic applications:


RSV in PS8WM

All-round material for light to heavy hydraulic applications with linear, short stroke or helical movements in mineral oils, flame retardant hydraulic fluids, phospate ester, bio-oils or fluids with low lubricating properties:

O-Ring NBR 70 Shore A N
FKM 70 Shore A V
Set Code PS8WMN or PS8WMV


RSV in PS61B

For medium to heavy applications with linear movements in mineral oils and other media with good lubrication:

O-Ring NBR 70 Shore A N
FKM 70 Shore A V
Set Code PS61BN or PS61BV

For specific applications, all PTFE materials are available.
