SUS Barrier Bearing

Deep Groove Ball Bearing, Spacea, SUS-Barrier

NSK SUS Barrier Bearings are part of the SPACEA™ anti-corrosion range of bearings. With a strong oxide layer on the surface of the martensite stainless steel bearing along with special surface treatment, corrosion resistance is greatly improved. Specifically designed for processing and production equipment where clean, vacuum, corrosive, sterilization and disinfection cycles, water, humidity and other demanding operating environments are required (i.e. conveyors in the fisheries industry- exposed to salt damage).
