Motor bearing,is a special bearing specially used in electric motors or motors. The bearing used in the motor is a part that supports the shaft, it can guide the rotation of the shaft, and it can also bear the idling parts on the shaft. The concept of bearing is very broad.
There are four types of bearings commonly used in motors, namely rolling bearings, sliding bearings, spherical plain bearings and oil-impregnated bearings. The most common motor bearings are rolling bearings, ie bearings with rolling elements.
Sliding bearings generally refer to bearings without rolling elements, that is, bearings for sliding motion, and some of them are Boundary Lubricants. 2. Motor bearings use smooth metal balls or rollers and lubricated inner and outer ring metal surfaces to reduce friction. These balls or rollers "carry" the load and support the motor shaft, allowing the motor (rotor) to rotate smoothly. Commonly used bearings in industrial motors are: deep groove ball bearings, cylindrical roller bearings, insulated bearings, ceramic bearings, etc.
