An Spanish Steel Mill Company was experiencing bearing life times much shorter than desired. The unexpected failure of the bearings caused production stoppages, causing lost time and money. NSK Technical Department together with the Steel Mill Technical Office analyzed the working conditions of the bearings as well as the lubrication regime. As a result of these analyses, several modifications were made such as review of the fitting, suitability of the lubricants as well as the use of HPS spherical roller bearings. With all the applied changes, the running life of the bearings was greatly extended.
