Judgment under the disassembly of INA bearings when can use again, check after the linear bearing cleaning, carefully check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, bearing clearance whether to increase, and presence of falling damage, abnormal size precision.
Non separation of small ball bearings, etc. , the inner ring with one hand flat end, rotate the outer ring confirm whether smooth.
This type of bearings bearing separation, rolling body, the outer ring raceway surface can be respectively.
Large bearing can't rotate with the hand, pay attention to check the rolling element and raceway surface, cage and guard surface appearance, bearing the importance of the higher, the need to be careful to check.
Judge INA bearings can use again, according to the damage degree of linear bearing, mechanical properties, importance, and operating conditions, the factors related to inspection cycle to decide.
But check if found any of the following defects, the bearing can't continue to use, need to replace new bearing.
INA bearings 6 note 1 preventive maintenance.
Raceway surface, guard, significant roller card.
2.
Maintains a badly worn or loose rivet badly.
3.
Raceway surface, rust and roller has a scar.
4.
Rolling surface, have significant indentation rolling body, and make a mark.
5.
Inner ring diameter or outer diameter on the creep.
6.
Inner and outer ring, rolling body any one strip.
