Simrit Freudenberg Oil Seals and Industrial Sealing Solutions
Simrit Freudenberg oil seals are technical sealing solutions used in industrial machinery, gearboxes, motors, drive systems, hydraulics and many other demanding applications. Particularly important are radial shaft seals and Simmerring® seals, designed to seal the interface between a rotating shaft and stationary housing while retaining lubricant and helping protect mechanical components against contamination.
Freudenberg is one of the world's leading specialists in sealing technology. Today, this expertise is represented by Freudenberg Sealing Technologies, which develops static and dynamic sealing solutions for automotive and general industrial applications.
Simrit and Freudenberg
The Simrit name has a long history within Freudenberg sealing technology and remains well recognized by industrial customers, maintenance departments and repair companies searching for replacement seals.
Products may therefore be searched under several related terms:
- Simrit
- Simrit Freudenberg
- Freudenberg
- Simrit oil seal
- Freudenberg oil seal
- Simmerring
- radial shaft seal
When identifying a replacement, the original designation should be checked together with the dimensions, material and seal design.
Simmerring - Freudenberg Sealing Technology Since 1932
The history behind the product is particularly important.
The original Simmerring® was developed by Freudenberg in 1932 as a sealing solution for rotating shafts. Its name originated from Freudenberg engineer Walther Simmer. In 1936, Freudenberg developed a version using a synthetic NBR sealing lip, representing an important step in the development of modern radial shaft seals.
The term "simmering" has since become commonly associated with rotary shaft seals in several European markets, while Simmerring® remains historically connected with Freudenberg.
Simrit Freudenberg Radial Shaft Seals
A radial shaft seal operates between a rotating shaft and stationary housing.
Its principal functions can include:
- retaining oil or grease
- reducing lubricant leakage
- protecting mechanical components
- limiting contamination ingress
- sealing rotating shafts
These seals are widely used wherever a rotating shaft passes through a housing containing lubricant.
Simrit Seals for Industrial Machinery
Simrit and Freudenberg sealing solutions are relevant to a wide range of applications, including:
- industrial machinery
- gearboxes
- electric motors
- drive systems
- automotive equipment
- hydraulic systems
- pneumatic systems
- agricultural machinery
- construction machinery
The exact seal design and material should always be matched to the operating environment.
Simrit Freudenberg Sealing Materials
Depending on the specific product and application, technical seals may use different elastomers and engineering materials.
NBR - widely used for conventional oil and grease sealing applications.
FKM (FPM) - suitable for applications requiring increased temperature capability and resistance to many oils, fuels and chemicals.
EPDM - commonly selected for applications involving water, steam and weather exposure.
VMQ - silicone elastomer used where a broad temperature range is important.
PTFE - used in specialized sealing designs requiring low friction or broad chemical resistance.
Material compatibility must always be verified for the specific medium and operating conditions.
How to Select a Simrit Oil Seal
Correct seal selection requires more than matching dimensions.
Check:
Dimensions: shaft diameter, housing bore and seal width.
Designation: product number or marking on the original seal.
Material: NBR, FKM, EPDM, VMQ, PTFE or another specified compound.
Medium: oil, grease, water, fuel or another process fluid.
Temperature: minimum, normal and maximum operating temperature.
Shaft Speed: particularly important for dynamic radial shaft seals.
Seal Design: primary lip, additional dust lip and other construction features.
Two seals with identical dimensions are not necessarily interchangeable.
