Atlas Spherical Bearings

Atlas Spherical Bearings consist of a concave backing plate and a convex plate is placed on top of this, which, thanks to its polished hard-chromium plated surface, can slide within the lower part, thus allowing rotations about every axis. The curved contact surface has low friction which is achieved by means of PTFE that is bonded to the concave surface and is in contact with hard-chromium plated surface. Sliding capabilities in a horizontal direction are provided by incorporating a plane sliding interface at the top of the bearing. This flat sliding surface is achieved by the use of PTFE.
