Spherical plain bearings are designed to accommodate the operation of shafts or rods amidst varying degrees of misalignment. They are engineered to withstand high radial loads and maintain stable performance under demanding conditions, such as boundary lubrication, extremely high speeds, and critical application stresses. These bearings consist of an inner ring with a spherical convex outer surface and an outer ring with a corresponding spherical concave inner surface. This design makes them particularly suitable for bearing arrangements that require accommodating misalignment between the shaft and the housing, or involve oscillating or repetitive tilting movements at relatively low sliding speeds.
