Rod Seals · REM

Operating Conditions
Pressure | Up to 60 MPa |
Speed | Up to 15 m/s with linear movements, frequency up to 5 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 Recommendation, 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:
