NSK Industries - Ink Pad Roller: A magazine priniting company was using open Deep Groove Ball Bearings in an ink pad roller application. NSK recommended Deep Groove Ball Bearings with DDU seals, resulting in no bearing failures reported within a month.
NSK Industries - Conveyor: One potash processing plant had problems with chain conveyor's plummer blocks equipped with tapered roller bearings. The bearings failed several times per year due to tough operation conditions (production dust, high shaft temperature).
