The customer was experiencing regular bearing failure on their conveyor at a Milk Processing Plant. The bearings were in an inaccessible area and were difficult to lubricate. The customer had to change the bearings every 10 weeks, resulting in down-time of 3 hours at least twice a year. NSK reviewed the bearing application and suggested that Stainless steel bearing inserts fitted with Molded-Oil would give a better service life. They combined these with the additional benefits of Silver-Lube® polymer housings to provide the Life-Lube® combination. Trials showed that bearing life was extended from 10 weeks to over 1 year.
