Stainless steel Spacea series bearings equipped with Molded Oil solid lubricant from NSK have been specified to solve a problem of premature deep-groove ball-bearing failures at a petrochemical plant in Spain.

The bearings are directly in contact with water, hydrocarbons and particles in suspension from the production process and the ingress of these contaminants was causing the original bearings to fail within a year.

To solve the problem, NSK’s engineers recommended the Spacea bearings with DDU-type contact seals to deny contaminant ingress. To ensure effective lubrication under extreme working conditions, Molded Oil was recommended.

The bearings specified for this application are manufactured with outer and inner rings and balls of Martensite stainless steel for maximum corrosion resistance.

Key benefits of product application

  • The Spacea bearings have reduced unplanned maintenance and production downtime.
  • They are providing high performance and reliability under demanding operating conditions.
  • The Molded Oil bearing lubricant is said to be ideal for water- and dust-contaminated environments.
  • To date, the bearings have performed for more than one year without problems, exceeding the bearing life originally targeted.
