A cement customer was experiencing repeated bearing failure on the blade support of a concrete pipe slotting machine. The failures were occurring every 2-3 months, causing 8 hours downtime per failure. NSK Engineers examined the application and determined that ingress of concrete dust was causing premature failure of the bearings. NSK recommended upgrading to Molded-Oil bearings, which would offer better service life. The change in bearing resulted in improved bearing performance with life increasing from 2-3 months to 12 months.
