A spherical plain bearing is a type of mechanical bearing used to accommodate rotating or oscillating movement between two components. It consists of two essential components: an inner ring and an outer ring, both of which have spherical surfaces. The inner ring is usually attached to the shaft, while the outer ring is attached to the housing or the structure. The spherical shape of the bearing allows it to tilt and rotate, compensating for any misalignment between the shaft and housing.
