Corrosion-resistant thin ring taper roller bearing for use in e.g. medical field, has bearing disks made of nitrogenized stainless steel, and rollers made of nitrogenized stainless steel, ceramics or silicon nitride

摘要

The bearing has two isometric and identically shaped bearing disks (2, 3) tapering conically with respect to diameter, and rollers (5) guided into a plastic cage (4) and running between the bearing disks. The bearing disks are made of nitrogenized stainless steel, and the rollers are made of nitrogenized stainless steel, ceramics or silicon nitride. The cage is made of polyamide or polyether etherketone.
