Bearing the correct use , it can have a long life. If damage occurs turbocharger bearings 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 uneven .
methods . 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 insert ball bearing of fill ; setting the appropriate clearance ; check the conditions of use ; prevent bearing centerline tilt ; checking around the bearing design ;
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
Action: Re-select bearings ; reconsider clearance inspection shaft and bearing housing precision
