The rolling mill bearings on EDA bearings equipment regular maintenance, operation and peripheral parts change removed when stop check, the demand in turn discriminant time bearings parts can use and recording of again good from bad. Also responsible for investigation and records were broken down EDA bearings and appearance. The remaining amount, in order to clarify and visit the lubricant sampling back, good cleaning bearingss.

Then check the EDA bearings raceway surface, rolling surface and the surface condition and confrontation the wear condition has no damage and abnormal situation is special to see raceway orbit. Discrimination of rolling mill bearings can apply once again, in the thinking of bearings damage, mechanical function, first, operation conditions, check cycle back again choice.
Check the effect, if found EDA bearings damage and abnormal situation, please follow the bearings damage phenomenon to find out the reason, countermeasures. In addition, check the results, if there are some defects in it, rolling mill bearingss can not be used, the demand change to a new EDA bearings.
A. inner and outer ring, rolling body, confrontation one crack and presents the debris.
B. inner and outer ring, rolling body any split.
C. raceway and rib and rolling card significantly hurt.
D. confrontation serious wear or rivets loose ferocious.
E. raceway surface, rolling rust and bruises.
F. rolling, rolling a significant indentation and trace.
A creep of G. inner diameter of surface or outer diameter.
H. thermochromism ferocious.
Sealing grease I. bearingss seals and shields to serious damage.
