A confectionary manufacturer was experiencing short service life (only 3 months) from deep groove ball bearings used in a Dürr Head Wash application. Due to the high levels of water used in the process, water ingress into the bearings caused their premature failure. This resulted in costly downtime and loss of production. NSK recommended the use of Stainless Steel bearings fitted with Molded-Oil lubrication. These are designed to perform well in wet applications. Regular monitoring of the application showed that the bearing lifetime was extended to over 18 months which represented a significant improvement on the original design.
