NSK Bearings periodic inspection methods

Regular inspection of the bearings, bearings in the best condition for the maintenance is very important work, you can also find problems reflected. Bearing in use on the precautions and knowledge.
First of all, we want to stress is to keep the NSK bearing lubrication and clean is very important. So when we check NSK Bearings should be obtained before cleaning the surface of NSK bearings, and bearing surrounding the demolition of parts. We should note that seal is very fragile parts, and therefore need extra inspection and dismantling of care not to over-exertion, so as to avoid damage to parts. Then carefully check the NSK bearing oil seal and the surrounding parts, if shown a negative symptoms, be sure to replace the lost, poor seal will result in bearing damage to the unusual cloud NSK bearing equipment downtime caused by .

Secondly, we have to check the NSK bearing lubricant. Lubrication is very important, not only for the NSK bearings, but also for all the imported bearings. Note, however, FAG bearings should not add too much grease. NSK bearing lubricant on the inspection methods are:

Stained little lubricant in the friction between the two that, if contaminants exist, it can be felt out; or in the back of the hand painted a thin layer of lubricant, and then seal-ray examination.

Then is to replace the lubricant of the NSK Bearings.

NSK using oil lubricated bearings in addition to the old oil spilled after, if you can, should and then poured into the fresh oil and let it spin a few minutes at low speed. Residual oil to collect as much as possible contaminants, and then spilled addition to these oil. Note: The oil in the first filtered before use. The use of grease lubricated bearings NSK grease replacement when Joe used devices should be avoided except cotton material connected with the bearing angle to any part of NSK. Because these residual fibers may wedge in between rolling parts and cause damage, especially in the application of small bearings should pay more attention to this issue.

Finally, note that the cover exposed NSK bearings.

Check NSK bearings, do not let bearing exposure to environmental pollutants or moisture. If the work is interrupted, should be oiled paper covered plastic or similar material had the machine.

If possible without dismantling the case of carrying out inspections without masking the bearing cleaning, coated with a brush to coat with the oil solvent (white spirit) wash, then a dry cloth or lint with compressed air blowing stem (be careful not to start rotating bearing components). Similar to a small mirror and dental probe used to check that the orbital plane bearing, retainer and beads. If the bearings are not damaged, should be provided under the original machinery lubrication instructions or books from 204 to 247 re-lubrication of the implementation of recommendations.

Encryption is not clean or dust cover bearing; only its external surface can be polished. If the bearing was damaged when the case is dropped to be replaced. In the regular maintenance shutdown period of replacement front bearing than the damage due to sudden shutdown selected as the loss of much more economic.
