The rolling bearing, if not choose wrong frighten can used correctly, to INA import bearing life before, can use for a long time, in this case, the damage status for detachment.

On the other hand, there are unexpected early damage, and giving in to use the early damage, as the early damage causes, use the consideration on the lubrication not scared, and then and foreign invasion, INA import bearings of error and shaft assembly of large deflection of axial and bearing box, the research is not, etc. Can say, the reason of overlap between more.

So, to a full understanding of the bearings use machine, conditions of use, import bearings to peripheral INA structure to foundation, if can make clear the situation before and after accident, combining bearing damage and a variety of reasons are examined and can avoid the same accident happening again.

Equipment preventive maintenance, inspection and peripheral parts replacement operation was removed when the bearings of check formula, a judge could use again or use of good in bad. Investigate and record is broken down import bearings and appearance of the INA, in order to find out the rest of the lubricant and and the quantity, sampling later, will make good cleaning bearing.

Second check groove surface, face and cooperate with the rolling conditions and maintains a wear state for any damage and abnormal situation.

Judge INA import bearings can you use again, to the extent of the damage in considering bearing, the machine performance, importance, operation conditions, check again later period and so on to decide. Check the result, if found bearing have damage and the abnormal situation, hurt the content of the section to find out reason, establishing countermeasure. In addition, check the result, if there are some defects of words, bearing can't again used, need to change new INA import bearings.

A. inside and outside circle, rolling body, maintains a any a crack and appear the debris.

B. inside and outside circle, rolling body any a detachment.

C. groove surface, raised edge, roller card of significant injury.

D. keep frame of severe worn or rivets loose the severe.

E. groove surface, rust and roller a wound.

F. scroll roller surface, showed the indentation and hit the mark.

G. inner circle diameter surface or outer diameter on the creep.

H. overheating discoloration of severe.

I. grease purgeable bearing sealing and dust cover to serious damage.
