How can you tell if a motor bearing needs to be replaced?

Hello everyone, I am your old friend, and today we will talk about an important small part in motors - motor bearings. Although it is not very large, in the normal operation of motors, the motor bearing plays an indispensable role. Then how long can a motor bearing usually last?

According to a lot of experience and data summarization, the life of the motor bearing is usually between thousands of hours to several tens of thousands of hours, which may be a bit vague. In other words, it depends on how often and under what conditions you use the motor. If you run the motor under long-term high load, high temperature, or in a harsh environment, the life of the motor bearing will definitely be shorter. What are the signals that tell you that the motor bearing needs to be replaced?

1. Increased noise:

If the noisy sound of the motor suddenly increases, don't think it's the construction site next door that started work again. It may be that the motor bearing is the problem.

2. Increased vibration:

If you feel that the motor is not as stable as before and the vibration amplitude has increased, the motor bearing may have "lost its way".

3. Increased temperature:

If the internal temperature of the motor suddenly rises, pay attention to whether the motor bearing is overwearing? At this time, if you don't replace the bearing, it is very easy to damage it.

4. Loss of lubrication:

Regularly check the lubrication of the motor bearing, if you find that the lubricating oil has deteriorated or has run out, it means that you need to add lubricating oil or replace the bearing with a new one.

Many people don't pay much attention to motor bearings, thinking that it's just a small thing, and that it's not so good, they can make do with it. But once the motor bearing is damaged, it can be a big problem for the entire motor, and it can even burn out the motor, causing downtime and affecting production, which is not worth it.

Whether it is household appliances or industrial machinery, the bearing in the motor is very important. Pay attention to its state in daily life and regularly maintain it. Once you find abnormal signals such as noise, vibration, and temperature rise, don
