Radial spherical plain bearings

Radial spherical plain bearings belong to the category of spherical plain bearings. They have an inner ring with a convex, outwardly curved surface and an outer ring with a correspondingly concave, inwardly curved surface. These bearings are ideal for constructions that need to compensate for alignment movements between the shaft and housing or where vibration, rotation, and pivoting movements occur at relatively low speeds, often in combination with high loads. They can withstand high static loads, high alternating loads, and impact loads very well.

The radial spherical plain bearings are available in maintenance-free and maintenance-required versions. In the maintenance-required version, steel/steel or steel/bronze sliding pairings are used. These require regular maintenance and re-lubrication. For the maintenance-free version, the combination of PTFE/chrome steel is used, which does not require re-lubrication. However, maintenance-free radial spherical plain bearings are more sensitive to impact and alternating loads.
