FKM Fluoroelastomer Synthetic Rubber Seal With Exceptional Properties FKM Bearing Seals

FKM (Fluoroelastomer) is a synthetic rubber material known for its exceptional properties. Let’s explore FKM seals in more detail:

Material Description:
FKM is a copolymer made of highly fluorinated hydrocarbons.
It was developed during the 1950s to meet the demand for high-temperature-resistant seals, O-rings, and gaskets in industries like aerospace.
FKM seals exhibit excellent resistance to media, ozone, and aging.
The material remains stable when exposed to fuels, petroleum-based oils, and greases, as well as aliphatic and aromatic hydrocarbons1.
 

Temperature Range:
Fluoroelastomers can be used in a wide temperature range:From −25°C (−13°F) to 200°C (392°F).
Special types of FKM are even flexible at −40°C (−40°F)1.
 

Applications:
FKM is predominantly used for seals in various industries:Automotive and Commercial Vehicles: FKM seals are common in automotive applications due to their high rotational speeds and temperature resistance.
Petroleum Production: FKM is used in oil and gas applications.
Chemical Industry: FKM protects against aggressive media and high process temperatures (above 140°C or 284°F).
Aerospace: FKM seals are essential in aerospace components.
General Industry: For example, in radial shaft seal rings in pumps and transmissions.
 

New Developments:
The recently developed 75 FKM 239961 from Freudenberg Sealing Technologies meets regulatory requirements for materials in the food, beverage, and pharmaceutical industries.
It offers very high purity, excellent media resistance, and impressive temperature resistance.
Applications include static or dynamic seals, O-rings, and diaphragms.
In summary, FKM seals reliably protect applications in demanding environments, especially where aggressive media and high temperatures are involved. If you have any further questions or need additional information, feel free to ask!

Advantages

1. Sealing Function:

   • Rubber bearing seals are designed to create a barrier between the internal components of a bearing and the external environment.
   • The primary function is to seal the bearing, preventing contaminants (such as dust, dirt, and moisture) from entering.
   • The lip or sealing edge of the rubber seal makes direct contact with the shaft, ensuring an effective seal.

2. Isolation:

   • Rubber seals isolate the bearing components from external factors.
   • They prevent metal-to-metal contact, reducing wear and extending the bearing’s lifespan.

3. Vibration Damping:

   • These seals absorb vibrations and shocks.
   • By dampening vibrations, they contribute to noise reduction and overall system stability.

4. Weatherproofing:

   • Rubber bearing seals protect against weather elements such as rain, wind, and UV radiation.
   • They maintain the integrity of the bearing even in challenging environmental conditions.
