According to different types and structures, the bearing can bear radial load, axial load or combined load existing in the radial direction and the axial direction simultaneously. The bearing can generate self-lubrication in operation because the composite material is embedded on the outer spherical surface of the inner ring.
Rod end bearings are typically used for oscillating motion at relatively low speeds, but also for tilting motion within a certain angular range, and can still function properly when the bearing shaft is out of concentricity with the shaft housing bore.
