Radial Spherical Plain Bearings

Radial spherical plain bearings are specialised bearings designed to accommodate radial loads while allowing for angular misalignment between components. They feature a spherical sliding surface that provides flexibility in positioning and movement.

How do radial spherical plain bearings work and where are they used?

Radial spherical plain bearings have an outstanding load carrying capacity, as a result of having no rolling elements.

They are particularly suited to use in bearing arrangements where there is misalignment, deformation of the shaft or stresses. They can accommodate for tilting, oscillating and slewing movements. 

These bearings have a very high wear resistance, as well as being resistant to shock loads, making them ideal for arduous environments. 

Radial spherical plain bearings are used in a wide range of industries including agriculture & forestry, construction, mining & quarrying and metals. 

Radial Spherical Plain Bearings FAQs

What is a radial spherical plain bearing?

A radial spherical plain bearing is a bearing with a spherical inner ring and a concave outer ring that allows angular movement (misalignment) while carrying radial loads and, depending on design, moderate axial loads.

What loads can radial spherical plain bearings support?

They are primarily designed for:

  • High radial loads

  • Moderate axial loads (in both directions, depending on bearing type)

They are especially effective under static, oscillating, or slow rotational motion.
