ABSTRACT:
A method of manufacturing a spherical bearing rod end having an outer race member, an intermediate member of yieldable material within and supported by said outer race member and an inner race operationally supported by said intermediate member comprising preforming a rod end blank having a ball-like section at one end thereof, flattening the spherical section to form two enlarged faces, each face having an inwardly disposed annular dished portion whereby the material flows uniformly to the outer periphery of the faces to form a uniformly cold formed annular area, removing the inwardly disposed annular dished portion to form a bore through said faces thereby leaving said uniformly cold formed annular area to serve as the outer member, inserting in said bore said intermediate member and said inner race member, interlocking with mechanical interlocking means said intermediate member and inner race member within said bore to effect the bearing support of said inner race member within said intermediate member.
