On the bearing periodic inspection, to maintain bearing was in the best condition is very important work, also can reflect find out the problem. Bearing in use on the matters of attention shall be paid and relevant knowledge.

First, we want to emphasize, keep NSK bearing lubrication and clean is very important. So when we check NSK bearings,first cleaning NSK bearing surface , then remove the bearing surrounding parts. We should pay attention , oil seal is very weak parts, so in check and disassembling exceptionally careful when need, not excessive force, lest cause the damage of the parts. And then carefully check the oil seal NSK bearings and its surrounding parts, if has presented the adverse symptoms, be sure to replace, bad oil seal can lead to bearing damage, make NSK bearing cloud not normal and cause equipment down.

Second, we will check the NSK bearing lubricant. The lubrication is very important, not only is the NSK bearing on, but for all the import bearings.Please note, FAG shoulds not be too much with grease. NSK bearing on the checking method of lubricant :

With little lubricant in between two fingers friction, if has the pollutant exists, it can feel out; Or in hand back with a thin layer of lubricant, then check the sealing light.

Then replace the NSK bearing is the lubricant.

Use the NSK bearing lubrication oil used engine oil , if it could, should pull 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. Note: the oil before use best first is filtered. And use the NSK bearing grease lubrication slippery slide in the replacement of fat,in addition to the use of implement should avoid things with cotton pick cape to any part of the NSK bearings. Because the residue of fiber may wedge rolling piece in between and damage it, especially the application of small bearing more need to pay attention to this problem.

Finally, note that cover the NSK bearing exposure.

Check the NSK bearings, must not let bearing exposure to pollutants or moisture environment. If work disruptions, should be with the oil film or similar materials have the machine.

If be in need not remove and may carry out the inspection case no masking the bearings cleaning, apply to use 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 bearing component starting rotation). With a small mirror and similar dentist used to check the probe of the bearing surface, keep track, and beads. If the bearing is not damaged, should according to the original machine provided lubrication measures and lubrication.

 
Do not block or dust cleaning encryption of bearing; Wipe the external surface only can. If the bearing is damaged cases that need to replace it. In the regular maintenance of down time change bearing than because bearing damage the selected into battle of suddenly shutdown losses come more than economic.
