A leading producer of pork products was facing repeated bearing failures on 14 Meat Slicer Machines. Monthly bearing changeouts were necessary, leading to high maintenance costs and lengthy machine down time. NSK investigated the problem and determined that ingress of water and hard contaminants during daily machine wash down were causing the failures. NSK proposed a test with NSK Molded-Oil bearings resulting in a significant  life extension and cost saving.

Key Facts

  • 14 bearing failures monthly 
  • Approximately 168 man hours annually for replacement
  • Substantial machine down time, 3 hours per bearing and shaft change per machine.
  • NSK solution: Deep Groove Ball Bearings with Molded-Oil lubrication.
  • Significant bearing life improvement resulting in no failures over a 4 month period on each machine.
  • Productivity improvement.
  • Significant annual cost saving achieved.
  • Meat Slicer Machine
  • Deep Groove Ball Bearings with Molded-Oil

Value Proposals

  • Following repeated and costly bearing failures, the customer requested a solution to the problem on their Meat Former/Classifier/Slicing Machines.´
  • A Failed Bearing Analysis determined that the failures were due to water and hard particle ingress resulting in lubrication breakdown/washout.
  • A trial was proposed using NSK Molded-Oil Deep Groove Ball Bearings which proved to be successful. Bearing service life was extended significantly.
  • Molded-Oil bearings were then installed in all 14 machines. A reduction in machine down time and maintenance costs yielded significant additional annual cost savings.
