1、 Improper installation

1. Using brute force during installation and directly striking the bearing with a hammer can cause significant damage to the bearing; It is the main cause of deformation.

2. Inadequate installation, installation deviation or failure to install in bearing position, resulting in too small bearing clearance. The inner and outer rings are not at the same center of rotation, resulting in non concentricity.

Suggestion: Choose appropriate or professional bearing installation tools, and use specialized instruments for testing after installation.

2、 Poor lubrication

According to the investigation, poor lubrication is one of the main reasons for premature bearing damage. The main reasons include: failure to add lubricants or lubricating oil in a timely manner; Lubricants or lubricating oil not filled in place; Improper selection of lubricants or lubricants; Incorrect lubrication method, etc.

Suggestion: Choose the correct lubricant or oil and use the correct lubrication method.

3、 Pollution

Pollution can also cause premature damage to bearings, which refers to the entry of sand, dust, metal shavings, and other debris into the interior of the bearings. The main reasons include: opening the bearing packaging too early before use, causing pollution; Unclean working environment during installation, causing pollution; The working environment of bearings is not clean, and the working medium is contaminated.
