Why does the rolling bearing of the motor overheat

2. The fit between bearing and shaft, bearing and bearing housing is too tight or loose. In particular, too tight will make the bearing heat and expand, reduce the clearance, increase friction and cause overheating

3. The machining accuracy of other parts is not enough. For example, the two ends of the base (3) are lightweight. 2. The principle of the traditional power line zigzag testing machine. The principle of the traditional power line zigzag testing machine. Materials - make the home appliance more light and floating. Different shafts, the end cover lip and the bearing chamber from large to small, and processing ellipses can lead to overheating of the bearings

4. The quality of the bearing is poor, the clearance is too large, the raceway is not clean, rusted, and the rolling element is not round<①. Pressure plate (or beam) of mobile electronic tensile testing machine/p>

5. Poor lubrication, too much or too little lubrication, and dirty grease
