How to determine whether disassembled bearings can be reused

How to determine whether the disassembled bearings can be reused in the daily maintenance and regular inspection of equipment.
To determine whether bearings can be reused, the following key factors can be considered:

1. Appearance inspection of bearings: Check whether there is obvious wear, cracks, or deformation on the appearance of the bearings. If the appearance surface is flat, without cracks, and there is no obvious wear, it usually indicates that the bearing can be reused.

2. Smooth rotation inspection: Rotate the bearing to check for any abnormal noise, vibration, or jamming. If the rotation is smooth and there are no abnormalities, it may indicate that the bearing can still be used.

3. Bearing size measurement: Measure the size of the bearing to ensure that it is within the tolerance range specified by the manufacturer. If the size is normal, the bearing can be considered for reuse.

4. Working conditions and service life: Consider the service life of bearings and working conditions. If bearings frequently operate in high load, high temperature, or high-speed environments, they may need to be replaced more frequently.

Taking into account the above factors and consulting with professional technicians when necessary can more accurately determine whether bearings can be reused.
