A premium vegetable processing company was experiencing frequent bearing failure on a vegetable wash application. Failures caused significant downtime and reduced production. NSK carried out a bearing failure analysis revealing ingress of contamination leading to significant reduction in bearing time. NSK recommended NSK Life-Lube with Molded-Oil inserts. A trial was conducted demonstrating improved bearing life which reduced downtime, maintenance costs and increased productivity.
