Regular inspection of the bearing is an important task to maintain the bearing in its best condition. The best inspection time is to schedule a regular stop machine inspection period.
Importance of bearing cleanliness: It is important to keep the bearings and lubricant clean.
Clean the surface of the machine before inspection, and then disassemble the parts around the bearing.
The oil seal is a very fragile part, so it needs to be disassembled carefully. Do not apply excessive force. Then carefully check the oil seal and its surrounding parts. If any bad indication is displayed, it must be replaced. Because a problem oil seal will cause damage to the bearing. Even cause the machine to stop.
Check the lubricant: Apply a little lubricant and rub it between your fingers. If there is any impurities, you can feel it, or smear a thin layer of lubricant on the back of your hand, and then seal it for inspection.
Lubricant replacement:  The bearings of the oil lubrication are removed the old machine oil, if possible, fill in fresh machine oil and let the machine turns for a few minutes at a low speed. Try to collect the remaining impurities in the machine oil as much as possible, and then remove the machine oil again. The machine oil should be filtered before use.
Grease-lubricated bearings should avoid any part of the bearing with cotton material when changing the grease, because these small fibers may be into between the rolling parts and cause damage, especially for small bearings. Pay attention to this problem.
When inspecting the bearing, the exposed bearing should be covered. Never expose the bearing in a polluted or humid environment. If work is interrupted, the machine should be covered with greased paper or plastic sheet or similar material. If it is possible to perform inspection without disassembly bearing, bearing is cleaned by a brush with petroleum solvent , and then wiped dry with a lint-free cloth or dried with compressed air (Be careful not to start the bearing assembly to turn). 
Use a small mirror and a probe similar to that used by dentists to inspect the bearing track surface, bearing cage and balls.
Do not clean sealed covers or dust-proof bearings; just wipe the external surface.
If the bearing is damaged, it needs to be replaced. It is much more economical to replace the bearing during the regular maintenance period than the loss caused by the suddenly shutdown machine due to the damage of the bearing.
