Simmerring - the original product you can rely on.

Simmerrings attain reliable seals on all rotating shafts. Based on many years of experience and the very latest technology, rotary shaft seals feature high functional reliability, flexibility and can withstand extreme forces.

Constantly leading the way

Our well-known Simmerring evolved with each new technical advancement, such as the optimized sealing lip profiles. This allowed even greater performance reliability—across a wide range of applications.

For smooth operations, Simmerrings must closely meet varying application requirements such as:

• Diameter and rotational speed of the shaft
• Temperature
• Pressure
• Occurrence of soiling on the outside
• Occurrence of soiling in the unit to be sealed
• The media requiring sealing (lubricating oils or greases, other fluid, paste or gas media).
