Spherical plain bearings are designed to manage strong push and pull or radial loads at low revolutions with the ability to withstand misalignment of the shaft inserted in it. The most common use of this bearing is as part of a rod in the steering rack of an automobile. Spherical plain bearings are classified by their size and shape, as well as by their ability to handle loads and misalignment. They are made from hardened brass, steel over even stainless steel, and coated with materials such as molybdenum disulfide to reduce friction between the contacting inner and outer ring and thus reduce wear and increase life. To maintain lubrication between these two surfaces a seal is employed, which also protects from exterior contamination. With more seals, a spherical plain bearing can be completely maintenance free withholding all its lubrication; however, this limits the angle at which it can be misaligned. Depending on the application, the requirements of the bearing can become quite sophisticated and locating the perfect part can be difficult.
