Radial spherical plain bearings are ready-to-install, standardised machine parts that are used for slewing, tilting and rotating movements in connection with static or dynamic forces and low speeds. They consist of a hollow spherical outer ring and a ball joint (inner ring). The essential differences between the various series are the cubic capacity and the plain bearing pair (steel/steel, steel/brass, stainless steel/PTFE etc.). The different plain pairing variants determine whether a radial spherical plain bearing is maintenance-free or requires maintenance.
