How to choose both ends of the motor bearing?

The motor bearing is like the skeleton of the motor, and the efficient operation of the motor is inseparable from the support of the motor bearing. Motor bearings not only bear the weight of the rotating parts, but also reduce friction and allow the motor to run more smoothly. If the motor bearing is not selected properly, the motor may have various problems, such as increased noise, uneven operation, and even cause the motor to burn. Why should the motor bearings at both ends choose the same clearance?

The "clearance" here is simply understood as the clearance between the rolling element and the raceway inside the motor bearing. If this gap is suitable, the life of the motor bearing will be longer, and the operation of the motor will be more stable.

1. Balance load and reduce wear

Choosing motor bearings with the same clearance allows the load inside the motor to be distributed more evenly. If a motor bearing is loose and a motor bearing is tight, the load distribution is uneven, the wear is intensified, and the service life of the motor bearing is reduced.

2. Reduce vibration and noise

Motor bearings with different clearances will produce different vibration frequencies during operation, which will lead to noise during motor operation. If the bearing clearance at both ends of the motor is consistent, the motor will be quieter and smoother.

3. Improve operation accuracy

The motor needs high-precision operation, especially some high-precision equipment, which has higher requirements for the operation of bearings. Motor bearings with the same clearance can help maintain the high precision of the motor and avoid errors caused by deformation or inconsistent clearance.

When choosing motor bearings, if conditions permit, try to choose motor bearings with the same clearance at both ends. This not only makes the motor run more smoothly, reduces noise and vibration, but also extends the service life of the motor and motor bearings.
