Spherical Plain Bearing

The oscillating bearing is a specially structured sliding bearing with a simpler structure than that of a rolling bearing. The oscillating bearing, which mainly consists of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, can bear a higher load. According to the different types and structures, the oscillating bearing can bear a radial load, an axial load, or a radially and axially combined load. It is usually used for oscillating movement (viz. angular movement) with a lower speed. As the sliding surface is spherical, the oscillating bearing can also make titling movement (viz. aligning movement) within a certain angle. In this way, the oscillating bearing still can work in case of larger misalignment between the support axle and the axle housing hole.
