A processor of food products harvests baby leaf products for sale to leading supermarkets. Their leaf  harvester machine had a variety of low cost mounted unit bearings to support shafts of various sizes. During the harvesting season, the machine was subject to frequent bearing failures due to ingress of dirt and water. When a failure occured the harvesting machine was stopped while repair work was carried out. This lead to production losses and in some cases to spoil crops. NSK experts were asked to review the application and working environment. NSK recommended the mounted unit bearings be replaced with Silver-Lube with offered improved triple sealing arrangement with Stainless Steel Bearings. During the season after the replacement, only two failures occured, leading to productivity improvement and a significant reduction of costs.
