Rod end joint bearings are joint bearings with rod ends or mounted on rod ends, which belong to a class of joint bearings. The joint bearing is a spherical sliding bearing. The basic type is composed of inner and outer rings with spherical sliding spherical contact surfaces.
The joint bearing is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, which can withstand larger loads. According to its different types and structures, it can bear radial load, axial load or a combined load of both radial and axial.
