A customer was experiencing repeated bearing failure every 2-3 months, on the blade support of a concrete pipe slotting machine, with 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 changing to Molded-Oil bearings, which would give a better service life. This resulted in much improved performance with bearing life quadrupled from 2-3 months to 12 months.
