or
General
The elastomer groove ring RBR has a small profile width and is therefore especially suitable for telescopic cylinders. The additional support ring on the inner diameter prevents gap extrusion, reduces friction and thus increases the operating life.
Medium
Hydraulic fluids based on mineral oil, water and water-glycol emulsions
Material
Standard materials: NBR or FKM
Advantages
- high extrusion resistance
- can be easily adjusted to operating conditions by selecting different materials
- compact design (radial) due to small profile width.
Installation instructions
Due to its small profile width, this rod seal is sensitive to tolerance deviations and excessive tolerance play between piston and guide unit. Below a rod diameter of 30 mm, the installation space must be divided.
Area of application
Use in seals on plungers, piston rods (presses), valve slides; also well suited for valve spindles and rotating oil feedthroughs.
