In the manufacture of diamond bearings consisting of a supporting plate/ring having a plurality of recesses equally spaced therearound with insert members consisting of hardmetal or carbide studs, with planar faces of polycrystalline diamond, positioned therein, the diamond bearing faces are made co-planar by placing metal pads, preferably of brazing metal, in the bottom of each recess before insertion of the bearing studs, placing the assembly with the bearing faces on a smooth planar support, heating the assembly to a temperature at which the metal pads soften or melt and allowing the metal pads to extrude around and braze the bearing inserts in place. When the assembly has cooled, the bearing inserts have their diamond bearing faces locked in co-planar relation by the extruded metal from the metal pads.
