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