A major manufacturer of silicon wafers for microprocessors experienced a failure on their vacuum pumps which were equipped with NSK bearings. A proactive maintenance strategy needed to be integrated. After consultation with NSK, an AIP expert visited the site to perform a complete Condition Monitoring Service review of the plant. With the support of the CMS equipment it was possible to produce a plant health map. Over a period of several months NSK was able to help the customer to devise their predictive maintenance strategy using analysis from the measurements. The customer also purchased the same CMS equipment as NSK to take readings and shared these readings with NSK for expert analysis. This resulted in avoidance of a further unplanned pump failure, which would have caused significant scrap at a very high cost.
