A wire manufacturer in France was experiencing frequent damage on final products due to bearing failures within their wire guides where Deep Groove Ball Bearings were mounted. On average, the bearings failed every 6 weeks, incurring maintenance time and loss of production. The bearings were failing due to ingress of contamination behind the seals and NSK recommended to replace the existing bearings with Stainless Steel Deep Groove Ball Bearings with Molded-Oil lubrication and DDU seals.
