A vegetable-processing company was experiencing repeated ball bearing failures on their transport systems. NSK was asked to investigate the problem and offer a solution. It was determined that a large amount of water was entering the bearings and washing out valuable grease. NSK suggested the use of sealed, corrosion-resistant Molded-Oil Bearings. This solution allowed grease to remain in the bearings and increase bearing life. 

Key Facts

  • Conveyor belt
  • Vegetable processing
  • Frequent bearings failures
  • Service life of only 2 weeks
  • Increased service life required
  • NSK solution: Molded-Oil Bearings
  • Result: Bearing lifetime increased from 2 weeks to over 9 months
  • Conveyor Belt
  • Molded-Oil Bearings

Value Proposals

  • The investigation carried out by NSK revealed that severe water ingress was causing problems (grease being washed out of the bearings)
  • Use of corrosion-resistant Molded-Oil bearings
  • Service life was significantly increased
  • Cost saving realised

Product Features

  • Molded-Oil provides continuous lubrication supply
  • Stainless steel for corrosive environments
  • Grease-free property with no oil refilling keeps operating environments clean
  • Operating life more than twice as long as grease lubrication (in water or dust contaminated environments)
  • Contact-seal type available in standard inventory for ball bearings
  • Extended maintenance-free performance is acheived as Molded-Oil provides a continuous supply of lubricant.
  • Available for high speed applications
  • Available in ball bearing, spherical roller bearing and tapered roller bearings types
