PTFE Rotary Seal - Teflon Hydraulic Seal

Type TR

TR rotary seal is designed for internal sealing in bi-directional pressurization applications

  • Suitable for bi-directional pressurization applications
  • Common application includes rotating track bushings, swivel joints, hose reels, and in machine tool hydraulics
  • A wiper ring near opening is recommended if TR seal is used as an end seal.
  • Low wear
  • High extrusion and high temperature resistance

Application Range

  • Pressure: ≦ 300 bar
  • Temperature: -40℃ ~ 200℃
  • Speed: ≦ 1 m/s
  • Standard Material: Bronze filled PTFE + NBR
  • (Note: Other materials are available for specified conditions)

Common Applications

Infrastructure Industry
