INA bearing outlying parts of regular maintenance, operation and replacement of equipment bearing being removed for inspections from time to time, you need to determine whether INA bearing parts are reusable in turn good from bad and record usage. Also carefully investigated and INA bearing and appearance of the records were removed. In order to identify and investigate remaining amount of lubricant, after sampling, to wash well INA bearings.
Secondly check INA bearing Raceway surface, rolling surface and surface condition and cage wear, no damage and abnormalities in particular to observe the running track of the Raceway surface. Judgment bearing will use again, to bearing damage level of machine performance, importance, condition, inspection cycles later to decide.
Check the results, if when INA bearing is damaged and the anomalies are found, follow the phenomenon identified cause of bearing damage, to formulate policy responses. Also, check the results, if there is several defect, INA bearings, can no longer be used, and new bearing needs to be replaced.
A. inner and outer rings, rolling elements, cages any one there are cracks and debris.
B. inner and outer rings, rolling elements in which any split.
C. Raceway surface, rib, rolling card significantly hurt.
D. cage wearing serious or rivets loose badly.
E. rolling body Raceway surface, rust and bruises.
F. scroll, scroll bars, a significant indentation and trace on the body.
G. diameter of the inner ring, or creep on the outer ring outside diameter.
H. overheating color ill.
I. grease sealed bearings seals and shields damage to serious.
