Spherical Surface Solid Lubraicatnts Bearing

WZB-3QJ spherical bearing is a unit of 2 rings , outer ring. The outer ring is divided into two axial haives boht made of 45#quenched steel with a hardness up to HRC40-43 and whole surface will be bumished. In case under specific application, the inside surface outer ring is plated hardened chrone. The inner ring is made from a metal basis, which may be all bronze or high strength brass, embedded wuth solid lubricant on its outside surface.
