Success Story
Industry: Food & Beverage
Application: Carrot Washer
Cost Savings: € 12 139
Introduction
A premium vegetable processing company was experiencing frequent bearing failure on a vegetable wash application causing significant downtime and reduced production. NSK carried out a bearing failure analysis revealing ingress of contamination leading to significant reduction in life 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 generating a significant cost saving to the customer.
