live rolling raceway surface stripping

   NTN Precision bearing damage and countermeasures
      NTN Bearing the correct use , it can have a long life. If damage occurs prematurely , probably because selection errors, improper use or poor lubrication . Therefore, NTN bearings installed , we need to record the machine type, installation location, conditions of use and its surrounding complex , bearing damage through the study concluded the type of problem occurs when the use of the environment , in order to prevent the situation from happening again.
 Bearing operation can not be observed directly , but through the noise , vibration , temperature, Backing bearings lubricant known abnormal status . The following are common injuries and NTN Bearing countermeasures.
   1 Peel : live rolling raceway surface stripping , stripping was uneven .
 Cause: The load is too large , the use of bad ; poor installation ; shaft or bearing housing precision bad ; games is not enough ; dust into ; rust ; improper lubrication ; temperature rise in the case of lower hardness .
 Action: Re-select bearings ; reconsider clearance inspection shaft and bearing housing precision ; re-examine the conditions of use ; Check the installation method ; checking lubricants and lubrication methods .
 2 Burn : bearing severe temperature rise , resulting in burns, can not rotate.
 Cause: The clearance is too small ; lack of lubrication or improper lubricant ; roller tilt ; overload ; in the case of temperature rise , lower hardness .
 Action: Check the type of lubricant and make sure that the amount of fill ; setting the appropriate clearance ; check the conditions of use ; prevent bearing centerline tilt ; checking around the bearing design ;
3 cage damage : rivets loose or broken , cage rupture.
 Cause: The torque load is too large ; frequent changes in speed or high-speed rotation ; poor lubrication ; snaps into foreign body ; vibration ; poor installation .
 Action: Check lubrication conditions ; re-examine the choice of the cage ; check the conditions of use ; improved installation method.
 4 abrasion : There are two abrasive types, one , red wear particles generated with the surface , first , in the rolling body produces Brinell
 Reason: lack of interference ; bearing swivel inadequate ; insufficient lubrication ; variable load , charge stability vibration
 Action: Check the state interference and lubricants segment ; transportation inside and outside the ring packaged separately ; reselect lubricant ; bearing reselected.
