Bearing as one of the very important parts of mechanical equipment, almost in every kind of machine, machinery, equipment, and even toys we have seen it, and the more technical requirements of the machinery, the higher the accuracy and strength of bearing parts and other characteristics.

First, bearing deformation and error

1. When installing, use brute force to directly hit the bearing with a hammer to damage the bearing; Is the primary factor of forming deformation.

2. The installation is not in place, there is error in installation or it is not installed to the bearing position, forming too small bearing clearance. 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 at the end of installation.

Second, serious wear and tear

According to the investigation, poor lubrication is one of the primary factors to form premature bearing damage. Primary factors include: failure to fill lubricants or lubricants in time; The lubricant or lubricating oil is not filled in place; Improper selection of lubricant or lubricating oil; Lubrication method is not accurate and so on. Suggestion: select the right lubricant or lubricating oil and use the lubrication filling method.

Third, premature wear

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; Installation of the working environment is not clean, resulting in pollution; The working environment of bearings is not clean, and the working medium is polluted. Suggestion: Do not unpack the bearing before use; Keep it secure during installation

Fourth, fatigue damage

Fatigue failure is a common damage mode of 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.
