Oil Seal

 
Oil seals are rotary shaft seals that close a gap between stationary and moving components and prevent lubricant to escape and thus stop contamination through the clearance. There are different types of oil seals that fit a different application and surroundings and are made out of different materials. The right material and type of oil seal is determined by the application and the medium that will be used with the oil seal.

 

These are used on automotive engines and geared motors primarily to prevent oil leaks at the ends of rotating shafts and the intrusion of dust particles from outside.

The word “oil seal” is used to describe these products that seal oil. In addition to preventing fluids, such as lubricants and water, and gases used in mechanical products from leaking at their “gaps,” they also keep dust, dirt and sand particles from intruding from outside.
Seals are an indispensable means for sealing machines in a variety of fields, including automobiles, airplanes, ships, train cars, construction machines, agricultural machines, petrochemical plants, and home appliances.
