POWER TRANSMISSION DEVICE (Abstract of the Disclosure) A power transmission device which includes trunnion and bearing sets for transferring power from a power generating unit to an operating unit. In the preferred embodiment of the invention, a cross is provided with a plurality of trunnions which define transfer surfaces. A bearing member in the form of a cup is provided for each of the transfer surfaces. The bearing cup is defined by a plurality of internal bearing surfaces which are integral with the bearing cup sidewall and which contact the transfer surfaces of the cross. The bearing surfaces, in the preferred embodiment, are semi-circular in cross-section and make bearing contact with the essentially cylindrical transfer surface of the cross. The bearing cup is preferably fabricated using powder metallurgy techniques which advantageously form the integral bearing surfaces within the cup, thereby eliminating the necessity for the use of balls or needles in the cup.
