Joint Bearing

A spherical plain bearing, also known as a spherical plain bearing or spherical plain bearing, is a bearing that allows rotational motion between two parts. It consists of an inner ring with a spherical sliding surface and an outer ring with a corresponding spherical sliding surface. Sliding surfaces are usually made of self-lubricating materials such as PTFE (polytetrafluoroethylene) or metal alloys.Spherical plain bearings are commonly used in applications requiring articulating or angular motion, such as automotive suspension systems, steering linkages, and industrial machinery. They are designed to withstand heavy loads and accommodate misalignment between connected parts.The spherical shape of the bearing allows for smooth movement in multiple directions, enabling connected parts to rotate or pivot without binding or excessive friction. The self-lubricating properties of the sliding surfaces reduce the need for external lubrication, making spherical plain bearings low maintenance and suitable for use in environments where lubrication is difficult or impractical.
