Why do automobile hub bearings get hot

Automobile hub bearing heating causes:

1) Reason: low bearing accuracy

Methods: Bearing with specified precision grade was selected.

(2) Reason: the spindle is bent or the box hole is different

Method: Repair the main shaft or box.

(3) Reason: the belt is too tight

Method: Adjust the belt for proper tightness.

(4) Reason: poor lubrication

Method: Select the specified brand lubricating material and clean it properly.

(5) Reason: low assembly quality

Methods: To improve assembly quality.

(6) Reason: the inner shell of the bearing runs

Method: Replace bearing and related wear parts.

(7) too much axial force

Methods: The clearance of the seal ring should be cleaned and adjusted between 0.2 and 0.3mm, and the diameter of the impeller balance hole and the static balance value should be corrected.

(8) Bearing damage

Method: Replace the bearing.

I believe we all understand the cause of heat in automobile hub bearings. When our car is abnormal, we should check it in time, especially to pay more attention to automobile hub bearings, so as to avoid bigger things.
