A major producer of snack foods was experiencing frequent failures of bearings on their cutter line. This was investigated by NSK and found to be caused by grease wash out following the line wash down process. Routine planned maintenance was carried out every 6 weeks which included changing the bearings to prevent unplanned stoppage. However failure did also occur before this maintenance was carried out resulting in loss of production. NSK engineers proposed to replace the current bearings with NSK Life-Lube housed units which achieved a vast improvement in the bearing lifetime resulting in the reduction of maintenance costs and lost production costs.
