Description
Structural Design:
The GRS is a double-acting internal sealing rotary glide ring for rotary joints that make rotating or swinging motion.
This consists of one composite PTFE sealing ring and an elastomeric O-ring as a pre-load element.
It is suitable for applications where the pressure alternate from one side of the seal to the other side.
Summary of Advantages:
- Low friction coefficient; no stick-slip effect on starts up
- Excellent abrasion and extrusion resistance
- The grooves provide an integrated lubrication system
- Excellent dimensional stability
Typically made from polyurethane, alternative materials can be provided upon request to suit your specific needs.
