In-depth Analysis Of The Causes Of Early Damage To Bearings

1. Improper installation (about 16%)

1, The installation of the use of brute force, with a hammer directly hit the bearing bearing damage; Is the main cause of deformation.

2, the installation is not in place, installation deviation or not installed to the bearing position, NSK bearings - imported NSK bearings - imported bearings caused by bearing clearance is too small. Inner and outer circles are not in the same rotation center, resulting in different centers.

Suggestion: Select appropriate or professional bearing installation tools, and use special instruments to detect after installation.

2. Poor lubrication (about 36%)

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

Suggestion: choose the right lubricant or lubricating oil and use the right lubrication filling method.

3. Pollution (about 14%)

Pollution can also lead to premature bearing damage, pollution refers to dust, metal chips and so on into the bearing interior. The main reasons include: open the bearing packaging too early before use, causing pollution; NSK bearings - imported NSK bearings - imported bearings when the installation of the working environment is not clean, causing pollution; The working environment of bearings is not clean, and the working medium is polluted

Suggestion: Do not unpack the bearing before use; Keep the installation environment clean when installing, and clean the bearings to be used; Enhance the sealing device of bearings.

4. Fatigue (about 34%)

Fatigue failure is a common way of bearing damage imported bearings. Common reasons for fatigue failure may be: long-term overload operation of bearings; Not timely maintenance; Improper maintenance; Equipment aging.

Suggestion: Select the appropriate bearing type and replace the fatigue bearing regularly and in time.
