What are the general types of motor bearing failures? How should we handle it?

The shaft is supported by bearings to rotate, which is the heaviest part of the load and also a component that is prone to wear and tear.

(1) Fault inspection during operation: When the rolling bearing is out of oil, you will hear a creaking sound. If you hear discontinuous honking sounds, it may be due to the 

bearing steel ring breaking. When there are impurities such as sand and soil mixed inside the bearing or when the bearing parts are slightly worn, a slight noise will be produced. 

Inspection after disassembly: First, check the rolling element and inner and outer steel rings of the bearing for damage, rust, scars, etc. Then, pinch the inner ring of the bearing 

with your hand and flatten it. Use your other hand to push the outer steel ring with force. If the bearing is in good condition, the outer steel ring should rotate smoothly without 

any vibration or obvious jamming during rotation. If the outer steel ring does not regress after stopping rotation, it indicates that the bearing can no longer be used. Hold the

outer ring with your left hand and the inner steel ring with your right hand, pushing hard in all directions. If you feel loose when pushing, it means severe wear and tear.

(2) The rust spots on the outer surface of the repaired bearing can be wiped off with No. 00 sandpaper, and then cleaned in gasoline; When there are cracks, broken inner and 

outer rings, or excessive wear on the bearings, they should be replaced with new bearings. When replacing a new bearing, choose a bearing of the same model as the original one.
