Axial preload of motor bearings

Have you ever been distressed by the loud noise and high temperature of motor bearings? Have you also casually adjusted the preload of the motor bearing in order to expect to solve the problem, but found that the effect is not ideal? Don't worry, today we will delve into the correct adjustment method of motor bearing preload.

If the preload of the motor bearing is adjusted improperly, it will cause a series of problems. Excessive preload will lead to overheating of the bearing and increased wear, further affecting the normal operation and life of the motor. Too low preload will cause the bearing to loosen, even cause vibration, increase noise. These problems will affect the reliability and efficiency of the device, so that you can have a headache during use.

Many people in the face of the motor bearing preload problem, usually choose to adjust the preload at will, in order to achieve the best results. But this approach often leads to a lack of experience and expertise, which leads to more and more serious problems. So, how to solve this problem scientifically?

The correct adjustment method should be based on the actual use environment and equipment requirements. First, a professional measuring instrument (such as a tensiometer) is used to measure the preload of the bearing, and then a detailed adjustment is made according to the standards provided by the equipment manufacturer. In addition, the motor should be checked regularly to ensure that the preload is within the normal range to avoid changes in the preload due to long use time.

Through this scientific method, the operation of the equipment can be made more stable, the noise is reduced, and the life is extended. Not only that, the failure rate of the equipment is greatly reduced, improving the overall work efficiency.
