A premium snack processing company was experiencing frequent bearing failures on a potato wash application. Failures were causing significant downtime and reduced production. NSK carried out a bearing failure analysis revealing ingress of contamination leading to significant bearing life reduciton. NSK was asked for a solution to improve service life. A test with new beairngs resulted in an increase of bearing life by 2 times.

Key Facts

  • High volume potato cleaning line
  • Frequent bearing failure caused significant production downtime and high maintenance costs
  • Water and soil particle ingress
  • Application indoor and outdoor (climatic influences)
  • NSK’s solution: replacing standard ball bearing with NSK’s Molded-Oil ball bearing
  • No bearing failures for more than 8 months
  • Productivity improvement
  • Potato washing application
  • Molded Oil Bearing

Value Proposals

  • NSK engineering conducted a Bearing Failure Analysis showing ingress of contermination into the bearing (water / Soil)
  • Replacing the standard ball bearings with Molded-Oil ball bearings
  • A test was conducted resulting in an increase of bearing life from 4 months to over 8 months
  • The customer increased productivity and reduced maintenance costs
  • No re-lubrication necessary

Product Features

  • Molded-Oil provides continuous supply of lubrication oil
  • Stainless steel for corrosive environments
  • Grease-free property with no oil refilling keeps operating environments clean
