Conveyor application for a Quarrying and Mining company
History
An important Quarrying & Mining Company were having reliability issues with a conveyor application. The inserts were operating in a very harsh environment, exposed to water and abrasives particles. The bearings were assembled 5 metres above the ground, so the inspection and maintenance tasks were especially problematic, which created difficulty predicting premature failure.
Corrective Measures
Our NSK engineers assessed the situation and proposed to assemble Molded-Oil™ inserts. These bearings, still working today, have already exceeded the lifetime of the previous bearings 9 times.
