angular contact spherical plain bearings. These specialized bearings excel in managing combined loads, adeptly handling both radial and axial components. Featuring a split inner ring and a single-piece outer ring, they possess remarkable load-carrying capacity, especially when confronted with higher axial loads. Compared to their radial counterparts, angular contact spherical plain bearings demonstrate superior capabilities in such demanding situations.

Thrust Spherical Plain Bearing

Lastly, let’s turn our attention to thrust spherical plain bearings. Designed with the explicit purpose of dealing with axial loads, these bearings boast two flat raceways, expertly accommodating a spherical sliding surface in between. Thrust spherical plain bearings prove invaluable in applications characterized by high axial loads or axial misalignment.

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.
