First,carefully remove NSK bearings, surrounding parts, such as oil seal

Before inspection must first clean the surface, then remove the NSK bearing peripheral parts. Oil seal is very weak parts, so need to carefully remove, not excessive force, and then carefully check the oil seal and its surrounding the parts.

If oil seal has presented the adverse symptoms, be sure to replace it, because bad oil seal can lead to NSK bearing damage of equipment and strict downtime.

Second, be sure to cover the NSK bearing exposure

NSK bearings in check, must avoid NSK bearing exposure to pollutants or moisture environment. If work disruptions, should be with the oil film or similar materials have the machine.

Third, special situations of bearings cleaning

In need not remove and to carry out the inspection situation, cleaning the NSK bearing no masking, want in order to apply with brush with oil solvents (white spirit) cleaning, again with a piece of cloth wipe not burr or use compressed air is blown dry (don't let NSK bearings components starting rotation).

Forth, check the bearing of lubricant

With the hand first with little lubricant, and then in between two fingers friction, if has the pollutant exist, can feel it. Finally in hand back with a thin layer of lubricant, then check the sealing light.

Ffth, to replace the method of bearing lubricant

NSK bearing the oil lubrication oil used in diarrhea, if can, again into the fresh oil and let the machine in the low speed rotating a few minutes. Try as far as possible to collect residual oil pollution, and then spilled oil besides these, oil, before use best first is filtered.

Slide the NSK bearing grease in the replacement of a slippery fat to use when Joe in addition to implement should avoid things with cotton pick cape to any part of the NSK bearings, because of the remainder of the fiber may break into pieces and rolling damage, especially small NSK bearing more need to pay attention to the application of this problem.
