A customer experiened repeated bearing failures in conveyor rollers. They were changing approximately 36 bearings annually and failures were taking place about every 6 week. Investigations by NSK showed the failures were caused by the ingress of water and hard particulates. NSK recommended replacing the standard bearings with NSK Molded-Oil bearings. A test of the bearings was conducted and no failures have occurred in 2 years. This solution resulted in a significant cost savings.
