A cement plant in the US was experiencing premature bearing failures due to a contamination in their slurry pumps. Bearings were only lasting two to three months causing frequent downtime and high maintenance costs. NSK was contacted to evaluate the problem and the NSK engineers suggested an improved bearing design together with a recommendation to increase bearing fitting standards. After the implementation bearing life was doubled.
