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.

Food - Beverage, conveyor, cutter line
  • Cutter line
RHP Life-Lube Molded-Oil, Bearing Unit, cut, 874x555
  • NSK Life-Lube with Molded-Oil bearings insert

Key Facts

  • Cutter line application
  • Wash down process causeing bearing failures
  • High maintenance costs and loss of production
  • NSK solution: Life-Lube housed units
  • Significant improvement in bearing life
  • Reduction of bearing costs, downtime and maintenance labor

Value Proposals

  • NSK reviewed the application following a process map survey and discovered grease wash out issue
  • A test with NSK Life-Lube product was conducted
  • Test bearings were fitted and monitored for performance
  • After one year in service, the bearings were still performing with no failures
  • This success is now being shared in the other two lines for additional cost savings
