General
The rod seal profile E1R is a lip seal equipped with an additional thermoplastic support ring. This profile is used for larger gaps in the back of the seal or for higher pressures. In addition, the support ring provides guidance for the seal.
Medium
Hydraulic oils on mineral oil basis.
Material
Standard materials:
- Sealing ring: NBR with a hardness of approx. 85 Shore A. Special materials are available for high or low temperature applications.
- Support ring: Thermoplastic
Advantages
- versatile application range
- compact size
- available in many materials, NBR, FKM, EPDM
- also available in intermediate sizes
Installation instructions
This U-Cup is very easy to fit into closed grooves by kidney-shaped deformation from 25 mm nominal diameter, below this an open groove design is recommended depending on the position and seal cross-section. In special applications (high temperature, speed, specific pressure load or use in water, HFA, HFB fluids etc.) please contact our application engineering department.
Application area
Profile E1R is particularly suitable for piston rods and plungers. When specifying the seal for a particular diameter, preferably select the one with the largest cross-section.
