NSK has solved a recurring problem
that was causing downtime at a UK
refinery. The problem concerned a
centrifugal pump that was going
wrong on average three times a year.
A cylindrical roller bearing was failing following the transition from belt drive to direct drive on the pump. NSK engineers concluded that the change from belt to direct drive had reduced the radial load on the bearing, causing rollers to skid on the bearing's inner raceway.
NSK installed a lower friction deep groove ball bearing and, since then, there has not been a single failure.
