Motor bearings are parts used to support the motor shaft, and their main functions are:

1 Reduce friction and transfer load. Bearings operate using smooth metal balls or balls, as well as lubricated inner and outer metal surfaces, to reduce friction and transmit loads

2. Maintain the stability and accuracy of the motor. By installing bearings on the motor shaft, axial runout and vibration can be avoided, maintaining the stability and accuracy of the motor, and thereby improving the working efficiency and reliability of the motor

3. Extend the service life of the motor. High quality bearings have excellent wear resistance and fatigue resistance, which can effectively reduce bearing wear and vibration, thereby improving the service life of bearings and extending the service life of motors

4. Maintenance and lubrication. Regularly inspect, lubricate, clean and maintain the bearings to ensure their normal operation and prevent bearing failures from affecting the efficiency and reliability of the motor

5. Protect the motor. Bearings have certain waterproof, dustproof and other protective capabilities, which can effectively prevent dirt from the external environment from entering the interior of the motor, protect the motor, and thus avoid motor damage caused by bearing failures

In general, motor bearings, as an important component of the motor, play a crucial role in the normal operation of the motor. They ensure the stable operation of the motor, improve its working efficiency, extend its service life, and also provide effective protection for the motor
