A vegetable preparation manufacturer in the UK was experiencing frequent bearing failures within a rotary screen. Two Deep Groove Ball Bearings were mounted within each wheel, with two wheels per rotary screen. On average the bearings failed every 6 weeks, taking 1 hour each time to replace incurring a significant loss of production per day. The bearings were failing due to ingress of contamination behind the seals. NSK engineers performed an Application Review and recommended bearings be replaced with Stainless Steel Molded-Oil Deep Groove Ball Bearings with DDU seals.
