Different types of bearing seals and their functions

Bearing seals have the characteristics of preventing grease from catching fire, avoiding frequent refueling and having a simple structure. It is widely used in bearings.

Bearing seal, a bearing seal, in particular a ball bearing seal, the ball bearing seal is in a circular shape on an end face extending upwardly two into a circular projection, said smaller diameter projection of the inner diameter with the ball bearing inner ring outer diameter, said larger diameter projection with the ball bearing ball ring outer diameter; said seal inner bore diameter is not less than the ball bearing inner ring of the inner bore of the ball bearing.

Role of the bearing seal ring:

In order to protect the dustproof effect of the bearing, often see different bearings on the use of different bearing seals, such parts can make the bearing get a good sealing effect, indirectly so as to protect the use of the bearing effect and service life, Dongguan Lingna machinery here, to give you a list of the different types of bearing seals shape and the role of the target.

The role of different types of bearing seals:

1.V-type bearing seals.

V-shaped seal is a kind of axial role of elastic rubber seal, used as a rotary shaft without pressure seal. The sealing lip has good activity and adaptability, can compensate for large tolerances and angular deviations, can prevent internal grease or oil leakage to the outside, and can also prevent the invasion of external splash water or dust.

2.O-type bearing seal

O-ring is mainly used for static sealing and reciprocating motion sealing. When used for rotary motion sealing, it is limited to low-speed rotary sealing device.

3.Y-type bearing seal

Y type seal is widely used in reciprocating motion sealing device. In addition, there is a spring tension (spring accumulation) seal, which is a spring in the PTFE sealing material, there are O-type spring, V-type spring, U-type spring.
