OIL SEAL (Shaft seal)

An oil seal is a mechanical component that prevents the leakage of fluids such as oil or grease between a rotating shaft and a stationary housing. It also blocks the intrusion of external contaminants like dust and debris.

Also known as: Oil Retainer, Shaft Seal

​Material

The material of an oil seal is selected based on the application environment and operating conditions. The lip material is typically made from the following elastomers:

​

• NBR (Nitrile Rubber):
  The most commonly used material, offering excellent oil resistance and wear resistance.

• FKM (Fluoroelastomer):
  Known for its outstanding heat and chemical resistance; ideal for high-temperature or specialized environments.

• ACM (Acrylic Rubber):
  Provides good heat and oil resistance; often used in engine oil seals.

• Silicone Rubber:
  Excellent resistance to both high and low temperatures, suitable for extreme environmental conditions.
