Typically, in order to determine whether removing bearings normal, FAG bearings after a clean check. Check on Raceway surface, scroll, status of the mating surfaces, cages and wear, increased bearing clearance of injury not attributable to dimensional accuracy declined, the exception. Non-separation of small ball bearings, the inner ring support level with one hand, rotate the outer ring to confirm fluency. Separation of tapered roller bearings and other bearings, rolling element and the Raceway in the outer ring can be respectively checked. Larger bearings cannot rotate, check rolling element and the Raceway, cage, flange surface appearance, higher the importance of bearing shall be carefully inspected.
Secondly you need bearings dry after cleaning with a rag, soaked in antirust oil. In the process, completely with rust preventive oil contacts the bearing and keeps turning FAG bearing, so that formation oil-film antirust oil cover on the bearing surface, so as to achieve the purpose of Rust prevention.
Then need to be evenly coated with butter in the FAG bearing surfaces, including the inner and outer rings, wheels, retainer. And is wiping edges turning bearings, grease into the bearing, inadequate lubrication.
Bearings should be aware of the following considerations:
1, maintaining a clean bearing and its surroundings
　Even invisible smile dust into the bearings, also increases bearing wear, vibration and noise.
2, the use of installation should carefully
　Do not allow powerful punch, does not allow direct percussion with a hammer bearing and does not allow passing pressure by rolling.
3, the use of appropriate and accurate installation tools
　Using special tools as much as possible, avoid using things like fabric and fiber.
4, preventing corrosion of bearings
　When hands get FAG bearings directly, to fully wash away sweat on his hand, and coated with high quality mineral oil before operation, paying particular attention to rust in the rainy season and summer.
