In addition the remote location of the bearing meant that re-greasing was difficult and inconsistent. The combination of these adverse factors meant that bearings were failing regularly – three times a year on average - from seizure, resulting in conveyor downtime with consequential loss of production.In an effort to reduce or eliminate these costs altogether, the quarry operator turned to NSK’s cost saving programme for extraction industries. The programme is designed for end-user bearing customers in quarrying and mining industries. After surveying the application, NSK engineers recommended a switch to RHP Self-Lube bearings equipped with triple lip seals, together with a best practice lubrication regime. NSK claims the installation has increased bearing lifetime from an average of 4-months to over 2-years continuous operation.
