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