How to Judge the Quality of the Automobile Bearings by Their Appearance?


Bearings are not only widely used in various machines, but also automobile wheels. The main thing is to make them work normally. So how to judge the quality of automobile bearings from the appearance? The following points are the aspects needing attention in appearance inspection.


1. There are many kinds of cracks such as raw material cracks, forging cracks, heat treatment cracks, and grinding cracks. These cracks will become the source of stress concentration and rapidly expand during the operation of the bearing, causing the bearing to rupture, which will affect the life and work of the bearing. Security has a great impact.


2. Various mechanical scars like abrasion, scratches, and so on, will cause poor bearing installation. Besides, it will cause unbalanced load and stress concentration, and reduce rotation accuracy and service life.


3. Rust, black skin, and pitting, the latter two are defects that easily store moisture and dirt, and are most likely to develop into rust. Corrosion is a source of pollution that causes poor installation, early wear, and fatigue. Severe corrosion can cause automobile bearings to be scrapped.


4. Peeling and folding. The parts of these two defects are not firmly bonded to the base metal, and there are often decarburization or carbon-poor phenomena around them to varying degrees. The materials are easy to collapse, dent, or wear, which affects the life and accuracy of the auto wheel bearing.


5. The riveting or welding quality of the cage is mainly to observe whether the rivet head is offset, skewed, and loose, whether the welding position is correct, whether the welding point is too large or too small, and whether the welding is not strong or welding.


To judge the quality of automobile bearings, you can start from the appearance of cracks, pitting, peeling and folding, etc. If the rolling elements cannot be retained and can rotate freely, it will cause bearing noise and rotation accuracy to decrease. In severe cases, it may even cause mechanical failure.
