Causes of premature damage of angular contact ball bearing

1、 Improper equipment (about 16%)

1. When using brute force and hammering the bearing directly, the bearing will be damaged greatly, which is the primary cause of deformation.

2. Equipment is not in place, equipment error or not installed to the bearing position, resulting in bearing clearance is too small. The inner and outer rings are not in the same rotation center, forming different concentricity.

Proposition: select appropriate or professional bearing equipment, and use special instruments to test the equipment.

2、 Poor smoothness (about 50%)

According to the investigation, poor smoothness is one of the primary causes of bearing premature damage. The main reasons include: not timely filling of smooth agent or smooth oil; not filling in place of smooth agent or smooth oil; improper selection of smooth agent or smooth oil; incorrect smoothing method, etc.

Claim: choose the right smooth agent or smooth oil, use the right smooth filling method.

3、 Pollution (about 14%)

Pollution can also lead to premature bearing damage, pollution refers to dust, metal chips into the bearing interior. The main reasons include: opening the bearing package too early before use, causing pollution; the working environment of the equipment is not cleaned, causing pollution; the working environment of the bearing is not cleaned, causing pollution of the working medium, etc.

Suggestions: do not unpack the bearing before use; adhere to the cleaning of the equipment environment when using the equipment, and clean the bearing to be used; strengthen the sealing equipment of the bearing.

4、 Fatigue (about 34%)

Fatigue damage is a common method of bearing damage. The common causes of fatigue damage may be: Bearing overload operation for a long time; not timely repair; improper repair; equipment aging, etc.

Proposition: choose the right type of bearing, replace the tired bearing in time.

The main reason of bearing damage is the above reasons. If the bearing type selection is correct, the equipment method is correct, and the smoothing method and smoothing agent are selected correctly, the bearing can operate normally.
