What Are Spherical Plain Bearings?

Spherical plain bearings, also known as spherical plain bushings or spherical plain joints, are self-aligning plain bearings designed to accommodate angular misalignment. They consist of an inner ring, an outer ring, and a spherical sliding contact surface. These bearings are commonly used in applications where misalignment or oscillating movements occur.

A typical spherical plain bearing comprises an inner ring with an inner bore, an outer ring with an outer surface, and a sliding contact surface. The sliding contact surface may be lined with various materials to enhance performance, and one such material is graphite.
