For regular maintenance, operation of rolling bearing device and other external parts replacement when you check the roller bearing was removed, you need to determine whether the rolling bearing parts in sequence which can be used again and using good from bad. Also carefully investigate and rolling bearing and appearance of the records were removed. In order to identify and investigate the remaining quantity of lubricant, after sampling, to rolling bearing wash very well.
Secondly check the bearing Raceway surface, rolling and surface condition and wear of the cage has no harm especially to observe the Raceway surface anomalies and the running track. Judgment bearing will use again, to consider how bearing damages, machine performance, importance, condition, inspection cycles later to decide.
Inspection results, if rolling bearing is damaged and when anomalies are found, follow the identified causes of bearing damage, to formulate policy responses. Also, check the result, if there are several defects, ball bearings cannot be used, new bearing needs to be replaced.
A. inner and outer rings, rolling elements, cages any one have crack and fragment.
B. both within and outside of any one split ring, rolling elements.
C. Raceway surface, rib and rolling with significant injuries.
D. serious wear of the cage or rivets loose badly.
E. Raceway surface, rolling rust and scars.
F. a significant indentation on the rolling surface and rolling and hit mark.
G. on the inner or outer ring outside diameter inner diameter surface creep.
H. overheating color ill.
I. grease seals for sealed bearings and dust cap damaged seriously.
