The customer was experiencing failures every 4 – 6 weeks with ball bearing inserts on a food production conveyor line. Regular high pressure wash-downs led to corrosion, seal damage and grease wash-out from the bearings, resulting in regular maintenance and production downtime. NSK reviewed the bearing application and were able to recommend NSK Life-Lube® as a solution. Trial bearings were purchased and applied. This resulted in significant improvements in bearing life with no failures during the trial period. This solution increased reliability and reduced unplanned downtime resulting in a large cost saving.
