A German vegetable-processing company was experiencing repeated ball bearing failures on one of its transport systems. NSK was commissioned to investigate the problem. During the investigation it was determined that a large amount of water was entering the bearings and washing out the grease fill. Therefore, NSK suggested the use of sealed, corrosion-resistant Molded-Oil Bearings, thus increasing the bearing life from approximately 2 weeks to over 9 months.

Key Facts

  • Conveyor Belt
  • Processing of vegetables (foodstuffs)
  • Frequent failure of the standard bearings
  • Service life of the standard bearings only 2 weeks
  • Increased service life required
  • NSK solution: Molded-Oil Bearings
  • Result: Bearing lifetime increased from 2 weeks to over 9 months
