A large producer of fish products was experiencing repeated failures on their Scraped Surface Heat Exchangers. They were changing bearings every 8 weeks which involved high maintenance costs and a lengthy machine down time. NSK investigated and determined that hard contaminants were entering the bearing causing failure. They proposed a testing of NSK Molded-Oil bearings which resulted in immediate improvement and significant increase in beairng life.
