Modular radial shaft seal Simmerring® MSS7

Design Sketch
Installation Sketch

  • Combination of Simmerring and rubber liner
  • With tension spring
  • Axial protection lips on the race
  • With protective lip
  • Rubberized outer jacket
  • Good static sealing effect with low-viscosity or gaseous media
  • Suitable for heavy external dirt loading
  • Compensation of thermal expansion, e.g. in light metal housings, very good sealing effect with greater roughness and split housings
  • Long service life
Most commonly used in the following applications:
  • Dynamic sealing of rotating shafts, independent of direction of rotation
  • Good static seal between sealing lip and shaft at standstill
  • Protective lip on the radial shaft seal and axial protective lip on the race against dirt accumulation from outside, can lead to temperature increase due to stronger friction
  • Protective lip against dirt accumulation from outside
  • Rubberized outer jacket ensures tight fit and seal to housing bore
  • Self-retaining
  • Stronger friction can lead to temperature increase
