Several ways of vulnerable to angular contact ball

Improper installation (about 25%)

the use of brute force during installation, direct hammer knock on the bearing damage is the biggest, is the main cause of deformation; Installation is not in place, installation deviation or not installed to the bearing position, resulting in bearing clearance is too small, inner and outer rings are not in the same rotation center, resulting in different centers!

Poor lubrication (about 45%)

Poor lubrication is one of the main causes of premature bearing damage. It mainly includes; The lubricant or the lubricating oil is not filled in time, the lubricant or the lubricating oil is not filled in place, the type selection of the lubricant is improper, the lubrication mode is incorrect, and the sealing is not good!

Pollution (about 15%)

 Refers to dust, metal fines and other foreign bodies into the bearing. Including: the use of bearings before the premature opening of the pollution caused by packaging, installation of the working environment is not clean, the working medium pollution!

Fatigue (about 15%)

Bearing long-term overload operation, not timely maintenance or improper maintenance, equipment aging caused fatigue damage.

Generally, only about 15% of bearing damage belongs to normal service fatigue damage. Bearings can work for a long time if they are selected correctly, installed correctly, lubricated correctly and with the right lubricant.
