A Snack Foods Manufacturer was experiencing short service life (4 months) used within a 7 lane food processing conveyor system. Due to daily wash-down cycles, water ingress into the bearings caused premature failure. This resulted in costly maintenance, loss of production and damage to ancillary equipment including conveyor belts. NSK engineers reviewed the bearing application and recommended the use of Stainless Steel deep groove ball bearings with Molded-Oil lubrication and DDU seals. Regular monitoring of the application showed that the bearing lifetime was extended from just 4 months to 12 months.
