Radial shaft seal Simmerring® B2PT

Design Sketch
Installation Sketch

  • Without tension spring
  • Without protective lip
  • PTFE sealing lip without spring
  • Open metallic outer jacket
  • High chemical resistance
  • Low friction
  • Suitable for dry running and deficient ulbrication
  • Suitable for high-temperature applications
  • Anti-adhesive (stick-slip-free behavior)
  • No stick-slip effect
  • Tight fit in installation space (interference fit)
  • Longest service life
Most commonly used in the following applications:
  • Dynamic sealing of rotating shafts, independent of direction of rotation
  • Metallic outer jacket ensures tight and precise fit
  • Self-retaining
  • Stiffening plate ensures increased rigidity
  • Only limited static sealing between sealing lip and shaft at standstill
  • Design without tension spring creates less friction, but also less sealing effect
  • Limited sealing of low-viscosity and gaseous media and in split housings
  • Additional guling of the seal into the housing is recommended
