Rod Seals · RU6
Operating Conditions
| Pressure | Max. 25 MPa (as single element) |
| Speed | Up to 0.5 m/s |
| Temperature | Use in mineral oils: -20 °C to +110 °C |
| Media | Mineral oil-based hydraulic fluids. |
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.
Materials
The thermoplastic polyurethane material US1RD has a high abrasion resistance, a low compression set and exhibits a high resistance to clearance extrusion. The integrated O-Ring is an NBR with 70 shore A and a very low compression set.

| Set Code | US1RDN |
Seal Clearance
| Operating Max. Pressure | Radial Clearance Smax |
| MPa | |
| 16 | 0.60 |
| 25 | 0.50 |
The values for Smax given in this table apply to all types for the low-pressure side of the U-Cup. They are designed for an operating temperature of 60 °C. (for harsh conditions and high side loads the gap must be reduced by 50%)
