I. Improper equipment (about 16%)

1, the use of brute force equipment, with a hammer directly hitting the bearing bearing damage is the largest; Is the primary cause of deformation.

2. The equipment is not in place, the equipment has error or is not installed to the bearing position, and the bearing clearance is too small. Inner and outer circles are not in the same rotation, forming different centers.

Claim: select appropriate or professional bearing equipment, equipment to use special instruments at the end of detection.

Ii. Poor smoothness (about 50%)

According to the investigation, poor smoothness is one of the primary causes of premature bearing damage. The primary reason includes: not timely adding smoothing agent or smoothing oil; Smoothing agent or smoothing oil is not filled in place; Improper selection of smoothing agent or smoothing oil; The smoothing method is not correct and so on.

Claim: select the right smoothing agent or smoothing oil and use the right smoothing filling method.

Iii. Pollution (about 14%)

Pollution can also cause premature damage to bearings. Pollution refers to dust and metal chips entering the bearing. The main reasons include: premature opening of bearing packaging before use, forming pollution; The operating environment of the equipment is not cleaned, resulting in pollution; The working environment of bearings is not cleaned, and the working medium is polluted.

Claim: in the use of the best do not open the bearing packaging; When equipment, adhere to the cleaning of the equipment environment, and clean the bearings to be used; Enhance the sealing equipment of bearings.

4. Fatigue (34%)

Fatigue damage is a common damage method of bearings. Common reasons for fatigue damage may be: bearing overload operation for a long time; Not repaired in time; Improper repair; Equipment aging.

Claim: Select the appropriate bearing type and replace tired bearings on time.

The above are the most common causes of early damage of angular touch ball bearings; There are many reasons for the formation of bearing damage in the early stage. The above is the primary reason for thinking, and sometimes it may be the inductive reason. If the bearing is selected correctly, the equipment method is in place correctly, the smoothing method and the smoothing agent are selected correctly, the bearing can operate normally very often.
