Introduction

A wire manufacturer was experiencing frequent damage on final products due to bearing failures within their wire guides. Deep Groove Ball Bearings were used in the application and were failing on average every 6 weeks resulting in maintenance time and loss of production. Failure was a result of an ingress of contamination behind the bearing seals. NSK recommended replacement of the existing bearings with Stainless Steel Deep Groove Ball Bearings with Molded-Oil lubrication and DDU, double contact seals.
