product description:

      Shaft rotating cell to ring is made of a dynamic and filled PTFE material provide a resilient rubber O-rings, used hydraulic equipment operated rotary shaft helical rod support shaft seal. Since the rotating cell to ring with a larger radial compressive force, able to withstand high working pressure, wear-resistant, able to withstand most of the media, good chemical resistance and strong performance.

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