An oil seal is a sealing ring (also called a Simmer ring after the inventor), usually made of rubber or other plastics that meet the technical requirements. It is used to seal the rotating parts of a system with a maximum internal pressure of up to 0.1 MPa and is immersed, during operation, usually in a bath of lubricants, gasoline or water. Seals are most commonly used to seal shafts and transmission or drive systems of machinery and machines. Common types include cassette (two-part) seals, contour-spring sealing rings and part-metal housed seals.
Seals prevent oil or lubricant leaks and keep contaminants out of the system.
