Spherical plain bearings have an inner and outer ring with a sliding contact. There is also a regreasable or a maintenance-free version. As a result, spherical plain bearings can be simultaneously exposed to a high radial load and a uni-directional axial load. There are many different types of spherical plain bearing. Spherical plain bearings can generally be divided into two types, which are steel on steel types and maintenance-free types with different sliding surfaces where it is not necessary to lubricate them again. Spherical plain bearings are used throughout industry, but also in the civil sector. Spherical plain bearings are the solution for stress-free connections wherever misalignments of movement need to be absorbed.
