Hole rotating cell to ring is made of a dynamic and filled PTFE material provide a resilient rubber O-rings, used hydraulic equipment sealed rotary motion. Rotating cell to ring using a specially designed, primarily as a fulcrum spiral motion, or rotary piston, piston rod, shaft seals. Having a low friction, no stick-slip phenomenon, dynamic and static sealing effect, lubricated or non-lubricated time performance are good, simple installation of trench structure, high pressure working conditions adaptability.

Technical Specifications: Operating pressure: high pressure of up to 70MPa, line speed: up to 15m / s.
