How does fag bearing determine whether to replace it?

In fact, if it is not a major damage, you can continue to use it. Fag bearings can be used to determine the importance of damage to FAG bearings, mechanical properties, and operating conditions to determine the next maintenance period.
If you cannot use the following defects you must replace the new bearing:
(1) The ring breaks any scrolls.
(2) The cage is worn significantly or the rivet is loose.
(3) The raceway surface, the wall surface, and the rolling greatly hurt the card.
(4) Raceways, rolling indentations and traces of severe blows.
(5) Raceway, rolled on rust, and injured.
(6) The discoloration caused by the high temperature is obvious.
(7) The outer ring surface or the apparent creep inner diameter surface.
(8) Sealing grease bearing, sealing ring or dust cover is obviously damaged
