Radial Spherical Plain Bearings

Radial Spherical Plain Bearings

Radial spherical plain bearings have an inner ring with a sphered convex outside surface and an outer ring with a correspondingly sphered but concave inside surface. Their design makes them particularly suitable for bearing arrangements where alignment movements between shaft and housing must be accommodated or oscillating or recurrent tilting or slewing movements must be permitted at relatively slow sliding speeds.

Radial Spherical Plain Bearings

Radial spherical plain bearings have an inner ring with a sphered convex outside surface and an outer ring with a correspondingly sphered but concave inside surface. Their design makes them particularly suitable for bearing arrangements where alignment movements between shaft and housing must be accommodated or oscillating or recurrent tilting or slewing movements must be permitted at relatively slow sliding speeds. Radial spherical plain bearings are available with different sliding contact surface combinations, i.e., the sliding surfaces of inner and outer rings are made from other materials. There are two main groups: spherical plain bearings requiring maintenance(steel-on-steel) and maintenance-free spherical plain bearings.

Radial spherical plain bearings requiring maintenance(steel-on-steel) generally have a hardened sliding contact surface on both rings. The characters are treated with molybdenum disulfide and phosphate. It has characteristics of wear resistance and wears corrosion. Bearings with this sliding contact surface combination require regular re-lubrication. The high strength of the sliding contact surfaces makes these bearings especially suitable for bearing arrangements where heavy loads of alternating direction, shock loads, or heavy static loads must be accommodated.
