Five Reasons For TIMKEN Bearing Overheating

The inspection of TIMKEN bearings should be carried out under a diffuse light, and the appearance, cracks and other parts of the TIMKEN bearings should be carefully observed.

1. Peeling and folding:
   The local combination of these two defects with the base metal is not strong, and there is often decarburization or carbon deficiency around them to varying degrees. The material is easy to collapse, dent or wear, which is very unfavorable to the life and precision of TIMKEN bearings.
2. The riveting or welding quality of the cage:
   Mainly observe whether the rivet head is offset, skewed, loose, lacking meat or double eyelids, whether the welding position is correct, whether the welding point is too large or too small, whether there is a phenomenon of rolling element stuck due to loose welding or excessive welding. The above items are the key parts we check when inspecting SKFTIMKEN bearings. In addition to the above-mentioned inspection parts, if the typing quality is poor, such as blurred or damaged handwriting, it should be considered as a defective product, and serious ones may not be accepted.
3. Rust, black skin and pitting:
   The latter two are defects that are easy to store moisture and dirt, and are most likely to develop into rust. Rust is the source of pollution that leads to poor installation, early wear and fatigue. Severe rust will make TIMKEN bearings scrapped.
4. Various mechanical scars:
   Such as abrasion, scratches, crushing, bumps, etc., will cause poor installation of TIMKEN bearings, causing eccentric loads and stress concentration, resulting in a decrease in rotation accuracy and service life.
5. Various cracks:
   Such as raw material cracks, forging cracks, heat treatment cracks and grinding cracks, etc. These cracks will become stress concentration sources and expand rapidly during the operation of TIMKEN bearings in the future, causing TIMKEN bearings to break, which has a great impact on the life and work safety of TIMKEN bearings.
