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 water levels used in the process, water ingress into the bearings caused premature failure. Costly downtime and loss of production was a result. NSK recommended the use of stainless steel bearings with Molded-Oil lubrication, designed to perform well in wet applications. Regular monitoring of the newly applied bearing in the application showed that the bearing lifetime was extended to over 18 months. This offered significant performance improvement from the original design.
