Within a big Automotive production plant the machine tool spindles often broke down due to spindle failures. The maintenance department of the production plant had to change the bearings every 2 weeks. The customer requested NSK to investigate the root cause of this bearing failure. After a survery of the complete application and the maintenance process the NSK engineers discovered that the main problem was incorrect handling of Super Precision Bearings during installation.
