A producer of frozen pizza was facing regular bearing failures with a belt tensioner on a food conveyor belt. The cleaning process of the production line with water was causing corrosion, grease washout and seal damage. The production line had to be stopped every 4 weeks in order to change the bearings. NSK reviewed the application and investigated the problem. NSK recommended to replace the exisiting bearings by Molded-Oil bearings. This resulted in a significiant lifetime extension and cost saving.
