Knuckle bearings is spherical sliding bearings,its basic type is composed of inner and outer ring which has the
contact surface of spherical sliding surface . Knuckle bearings is mainly composed of inner ring which has
spherical outside surface and a outer ring which has spherical inside surface, it can bear larger load.According to
its different type and structure, can bear radial load, axial load or radial, axial and existing joint load.Because the
spherical outer surface of inner ring with a composite material, so this bearing can produce self-lubricating
during the work . Generally it used to lower speed swing motion, also can be used for tilt movement in certain
Angle range.
Knuckle bearings are widely used in lower speed swing motion, tilt movement and rotation movement.
