Why do bearing parts have sealing rings?

Sealing rings, also known as shaft seals or oil seals, are a type of mechanical seal that are used to prevent the leakage of fluids from a rotating or reciprocating shaft. Sealing rings typically consist of a metal or plastic case, a flexible sealing lip, and a spring that helps to maintain pressure on the sealing lip.

Bearing parts have sealing rings to protect the bearings from contaminants such as dust, dirt, and moisture, which can cause premature wear and failure. Sealing rings provide a physical barrier between the bearing and its environment, preventing particles from entering the bearing and lubricant from leaking out. Sealing rings can also help to retain lubrication within the bearing, ensuring that it stays properly lubricated and reducing friction and wear.

In general, sealing rings play an important role in protecting the bearings from contaminants and moisture, improve their performance, and extend their service life.
