What problems should be paid attention to when replacing the grease of FAG bearings
 
Grease-lubricated FAG bearings should avoid contacting any part of the bearing with cotton when changing the grease, because these residual fibers may get stuck between the rolling parts and cause damage, especially in small FAG bearing applications. Please be aware of this issue.
 
Cover exposed FAG bearings
1. When inspecting FAG bearings, do not expose the bearings to pollutants or moisture. If work is interrupted, oil paper, plastic sheeting or similar materials should be used to cover the machine.
 
2. If the unprotected FAG bearing is cleaned without cleaning and can be inspected, please clean it with a brush dipped in petroleum solvent, and then dry it with a lint-free cloth or blow it dry with compressed air (be careful not to Let the bearing assembly blow dry). Start to rotate).
 
3. Use small mirrors and probes similar to those used by dentists to inspect the surface of the FAG bearing track, retainer and magnetic beads. If the bearing is not damaged, it should be relubricated according to the lubrication instructions provided by the machine manufacturer.
 
4. Do not use sealing caps or dust covers to clean FAG bearings; just wipe the outer surface.
 
If the FAG bearing is damaged, it needs to be replaced. It is much more economical to replace the bearings during regular shutdowns and maintenance than to stop suddenly due to bearing damage.
