Common damage of bearing cage

Cage as an important component of the bearing, its use is very important, bearing in the process of use, cage also often appear some damaged state, which will seriously affect the use effect of the bearing, and even lead to complete damage of the bearing can not be used, the following share about bearing cage common damage.

The common damages of bearing cage are as follows:

1. The damage of cage includes deformation, breakage and wear of cage

2. Column loss:

3. Deformation of the end face:

4. Wear of concave surface:

5. Wear of guide surface:

List the damage pictures of bearing cage:

Protection frame of deep groove ball bearing: concave part of steel plate stamping cage is damaged.

Cage of centripetal thrust angular contact bearing: fracture of cast iron cut cage concave column;

The reason is that the inner and outer rings are obliquely installed, resulting in abnormal load on the cage.

Cage of centripetal thrust angular contact bearing: the concave part of Cage cut by high strength brass casting is damaged.

Tapered roller bearing cage: steel plate stamping cage column damage.

The common causes of bearing cage damage are as follows:

1. Poor installation (non linearity of bearing).

2. Poor use.

3. The moment load is large.

4. The impact and vibration are large.

5. Excessive speed, rapid acceleration and deceleration.

6. Poor lubrication.

7. The temperature rises.

Common measures for bearing cage damage:

1. Check the installation method.

2. Check load, rotation and temperature conditions.

3. Reduce vibration.

4. Correct cage selection.

5. Change the lubricant and lubrication selection method.
