Radial Shaft Seals

Simmerrings seal rotating shafts reliably and are used in millions of applications and a variety of equipment in general industry and the automotive sector. This radial shaft seal ring is based on know-how gained from years of experience. It continually undergoes further refinement based on the latest technological developments, and is particularly functionally reliable, flexible and extremely stressable.

Freudenberg Sealing Technologies offers a comprehensive selection of products suited to a variety of requirements. The range is further expanded by creating combinations with other components and additional functions.

Simmerrings must be adapted to varying operating conditions to achieve friction-free operation:

  • Diameter and rotational speed of the shaft
  • Temperature
  • Pressure
  • Dirt accumulation from outside
  • Dirt accumulation in the assembly to be sealed
  • Media to be sealed off (lubricating oil or grease, other liquids, paste-like or gaseous media)
