What are the effects of a broken truck bearing?

Once a truck bearing is damaged or encounters unexpected situations, various abnormal phenomena such as machine and equipment stopping and function being damaged will occur. The following are the specific reasons for its damage: 

1. Metal corrosion occurs: If there is a lack of lubrication, it is easy to be oxidized and rusted by air. 

2. The bearing load is too large or used improperly: The load of the bearing cannot be exceeded during use. For example, if the cargo pulled by the car is too heavy, it is easy to damage the bearing. 

3. The bearing clearance is too small: The front wheel of the car uses an oblique thrust bearing, and the clearance needs to be adjusted. Too loose will cause abnormal noise, deviation, and wheel shaking. Too tight will accelerate wear. 

4. Use inferior bearings: The production process does not meet the requirements, the shaft or bearing box has poor precision, and the bearing steel has not been processed.

How to identify inferior bearings

‌Appearance inspection‌: Inferior bearings usually have a rough appearance, and there are defects such as wear and scratches on the surface.

‌Dimension measurement‌: Determine whether the size meets the standard by measuring the inner diameter, outer diameter and width of the bearing.

‌Weight check‌: The processing precision of inferior bearings is not high, and the weight is light, which is quite different from the weight of standard bearings.

‌Rotation check‌: Check the rotation resistance of the bearing by hand and whether the ball is stuck to judge the quality.

‌Sound check‌: Under normal circumstances, the bearing has no noise. If there is noise, it means that there is a quality problem‌.
