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

  • Molded-Oil Bearings

Key Facts

  • Food production conveyor
  • Bearing corrosion, seal damage and grease wash-out due to high pressure wash-downs
  • NSK Solution: Stainless steel Molded-Oil bearing inserts
  • 12 month trial on 10 bearings
  • Highly increased life-time: No failures after 12 months in operation
  • Cost reduced for replacement bearings, lubrication and maintenance
  • Productivity improvement

Value Proposals

  • NSK reviewed the bearing application and discovered that bearing corrosion and grease wash out were the main issues
  • A trial was proposed using Stainless steel Molded-Oil bearing inserts
  • After 12 months the bearings were still performing well with no failures
  • From this trial the solution was applied to other similar applications generating significant cost savings
  • This success was then transferred to other production sites within the company
