A German car manufacturer performed an annual audit on their machining centres. They found a high usage on their motor spindle bearings and contacted NSK to investigate this. NSK performed an application review and bearing examination which showed that the bearings were being subjected to external contamination which caused premature failure. To overcome this problem Sealed Super Precision Bearings were proposed. This had a dramatic effect on spindle performance with a large reduction in bearing failures and an increase in service lifetime from 12 to 36 months.
