To prevent thelubricating oil from leaking outside even under high pressure of the oil.

Classical oil seals consist of a metal housing that carries the dynamic sealing lip and provides the static sealing function. These are usually manufactured of elastomer material, such as ACM, Silicone or FPM. Further, since they are in contact with the surface of the rotating shaft, the lip is pressed onto the shaft surface by means of a spring ring.

Leather Oil Seals

The spring supplements the tightening force (i.e., the lip radial load) to ensure enhanced sealing performance and tight contact between the shaft and the sealing edge.The spring also prevents the deterioration of main lip sealing performance caused by high heat or other such factors. ×

Fundamental things and its importance 

 

NBR

Some disadvantages of NBR are poor ozone, sunlight and weather resistance as well as limited high temperature and flame resistance. For higher temperature resistance, a much better material to use is Silicone

elastomer, which is formed by the catalytic hydrogenation of butyronitrile rubber. Hydrogenation increases its
