improper installation (about 16%)

1. Brute force is used during installation, and hitting the bearing directly with a hammer will cause the greatest damage to the bearing;Is the main cause of deformation.

2. the installation is not in place, installation deviation or not installed to the bearing, resulting in the bearing clearance is too small.The inner and outer circles are not in the same center of rotation, resulting in different hearts.

Suggestion: select the appropriate or professional bearing installation tool and use the special instrument after installation.

Poor lubrication (about 50%)

According to the investigation, poor lubrication is one of the main causes of premature bearing damage.The main reasons include: not filling lubricant or lubricating oil in time;Lubricants or lubricants are not filled in place;Improper selection of lubricants or lubricants;Improper lubrication and so on.

Recommendation: select the right lubricant or lubricant, and use the correct lubrication filling method.

Pollution (about 14%)

Pollution can also lead to premature bearing damage, pollution refers to dust, metal chips into the bearing interior.The main causes include: premature opening of bearing packaging before use, resulting in pollution;The working environment is not clean during installation, resulting in pollution;The working environment of the bearing is not clean and the working medium is polluted.

Suggestion: it is better not to disassemble the packing of the bearing before use.Keep the installation environment clean and clean the bearings to be used;Reinforced bearing seal.

Fatigue (about 34%)

Fatigue damage is a common way of bearing damage.Common reasons for fatigue damage may be: bearing overload operation for a long time;Not repaired in time;Improper maintenance;Equipment aging and so on.
