Which are the points for attention in importing regular overhauling of the bearing?

While importing the bearing to check, the ones that need to judge sequentially imported bearing part once can use and record operating position again are bad. Also investigate and record imported bearing and appearance situation dismantled carefully. In order to clarify and investigate the overmeasure of lubricant, after taking a sample, should well wash and import the bearing.

Secondly check the ball track surface which is imported the bearing, rolling surface and cooperate with the intersection of Taxi and state, and the intersection of abrasion and state,etc. of retainer have zero damage and abnormal circumstance especially want, observe the intersection of ball track and the intersection of Taxi and running orbit. Judge whether the bearing could use again, consider the intensity that the bearing is being damaged, machine characteristic, importance, operating condition, checking cycle,etc. determine.

Inspection result, if find while having damaging and abnormal circumstances to import the bearing, please find out the reason according to the phenomenon that the bearing damage, make the countermeasure. In addition, inspection result, if had following several kinds defect, the imported bearing can’t be reused, need to change the new bearing.

1.The intersection of ball track and surface, block, have that display card injure by rolling element.

2.The abrasion of the retainer is serious or the rivet became flexible terribly.

3.The surface of ball track, rolling element get rusty and have scar.

4.Show the impression and make mark on rolling surface, rolling element.

5.Any has crackle and presents chip among Internal and external cycle, rolling element, retainer.

6.Any has the one that strips among Internal and external cycle, rolling element.

7.There is the one that creeps the internal diameter of inner circle or on the outer lane external diameter.

8.Pass thermo-color terribly.

9 grease seals the sealed cycle sum dust cap damage of the bearing severely.
