Why is the new bearing not flexible?

When testing new motor bearings, have you ever encountered the problem of inflexible rotation? Bearing rotation is not flexible will not only affect the normal operation of the equipment, but also may cause greater problems. Today, we will reveal the causes that can cause new motor bearings to turn inflexibly, and provide specific and practical solutions to help you quickly locate the problem and fix it.

1. Improper bearing lubrication

The new motor bearing may lack enough lubricating oil or the lubricating oil does not meet the working condition. It is recommended to ask the manufacturer about lubrication to ensure that the appropriate lubricant is used and the recommended amount is added.

2. Improper installation

Motor bearings are not aligned or stressed unevenly during installation. It is recommended to use professional installation tools and methods to ensure the correct installation of motor bearings.

3. Foreign body contamination

Foreign objects are introduced during production or installation. It is recommended to remove the motor bearing and pay attention to the health of the working environment when installing it again.

4. Size deviation

The dimensions of motor bearings or related components are out of tolerance. It is recommended to use a measuring tool to carefully measure the size of the motor bearing and its matching parts to ensure that the specifications are met.

5. The precision of motor bearing mating parts is insufficient

The shaft or seat hole matching with the motor bearing is not accurate enough. It is recommended to confirm the technical specifications of the parts with the supplier or rework them to meet the accuracy requirements.

6. Excessive preloading force

The preload applied during installation is too large, resulting in the motor bearing running inflexible. It is recommended to use appropriate tools and methods to adjust the preload to the recommended value.

7. Motor bearing type selection error

An unsuitable motor bearing type was selected. It is recommended to re-select the appropriate motor bearing type according to the specific working conditions.

The problem of inflexible rotation of the new bearing is not terrible, as long as the problem is identified and the correct method is used to solve it, it can restore its normal performance. By cleaning the bearing, checking the lubricant, proper installation and other steps, you will find that the problem can be solved.
