Is there anything to pay attention to when cleaning the bearing?

The cleaning quality of the bearing depends on the hand feel inspection. After the bearing is cleaned, carefully observe that there is always some residual oil in the gap between the inner and outer race raceway, rolling element and cage. During inspection, you can scrape off the remaining oil with a clean feeler gauge, apply it on your thumb and rub it back and forth slowly with your index finger. If there is a rustling sound between fingers, it means that the bearing is not cleaned and should be washed again. Finally, hold the bearing in your hand, hold the inner ring, move the outer ring to rotate horizontally, and it is qualified to be flexible, non blocking and non jumping.
For cleaned bearings, after filling with lubricant, they shall be placed on the assembly platform, padded with clean cloth or paper pad and covered with plastic cloth. When they are to be assembled, they shall not be placed on the ground or box. When moving the bearing, it is not allowed to hold it directly by hand. You should wear canvas gloves or wrap the bearing with a clean cloth before taking it. Otherwise, because there is sweat and moisture on your hand, it is easy to produce fingerprint rust on the bearing after contact. For bearings with dust covers or sealing rings on both sides and bearings coated with antirust and lubricating oil, do not clean them before installation because grease has been injected during the manufacturing process.
matters needing attention
1. For bearings with separable inner and outer rings, do not replace the outer ring to avoid errors affecting the contact quality.
2. For self-aligning ball and roller bearings, the rolling elements in the bearing shall not be taken out and mixed at will, so as not to affect the accuracy due to the confusion of installation position.
3. When installing the bearing, in order to check the bearing code and avoid installation errors, the typing surface of the bearing ring shall be placed and installed outward.
4. Heating of bearing and bearing seat shell hole for medium and large bearings with large interference, heating must be carried out before installation in order to facilitate installation; For the closely matched light metal bearing pedestal shell hole (such as aluminum bearing pedestal), due to its low hardness, in order to prevent the surface of the bearing pedestal shell hole from being scratched and roughened when the bearing outer ring is pressed in, it should also be heated and installed.
