1.The main function of motor bearings is to reduce friction and load during movement. In practical applications, motor bearings may be deformed for various reasons, which will not only affect their performance, but also may lead to the failure of the entire mechanical equipment.

 2.One of the main causes of motor bearing deformation is overload. When the load borne by the motor bearing exceeds its design limit, the internal ball or raceway may undergo plastic deformation, resulting in changes in the overall structure of the motor bearing. This deformation will make the clearance of the motor bearing increase, and then reduce its rotation accuracy and service life.

3.Temperature change is also an important factor leading to motor bearing deformation. In a high temperature environment, the material of the motor bearing may expand, resulting in changes in the internal structure. At low temperatures, the shrinkage of the material may also cause the deformation of the motor bearing. In addition, the sharp change in temperature may also cause thermal stress of the motor bearing material, further aggravating the degree of deformation.

 4.Insufficient lubrication is also one of the causes of motor bearing deformation. Proper lubrication can reduce the friction and wear inside the motor bearing and maintain its normal working state. If the lubrication is insufficient, the friction inside the motor bearing will increase, generating a lot of heat, if the heat is not distributed in time, it will lead to the temperature of the motor bearing rising, resulting in deformation.

5.Manufacturing defects are also an important cause of motor bearing deformation. If in the manufacturing process, the material selection of the motor bearing is improper, the processing accuracy is not enough or the heat treatment process is unreasonable, it may lead to the deformation of the motor bearing during use.

6.In order to reduce the occurrence of motor bearing deformation, we need to take a series of preventive measures. First of all, it is necessary to ensure the correct selection of motor bearings to avoid overload use. Secondly, to maintain good lubrication conditions, regularly check and replace the lubricating oil. In addition, regular inspection and maintenance of motor bearings should be carried out to discover and deal with potential problems in a timely manner. Finally, it is necessary to choose high-quality motor bearing products to avoid deformation problems caused by manufacturing defects.
