Spherical plain bearing PB series

swivelsteelcopper

With model PB, a copper alloy with high conformability is inserted between the steel outer ring and the spherical inner ring, in which only the spherical area is hard chrome plated. This structure makes this model a highly rigid Spherical Plain Bearing with high corrosion resistance and high wear resistance. The oil groove and the greasing hole on the outer ring allow grease to be applied to the sliding surface as necessary.
