ABSTRACT:
An electric motor that includes a case having an axially oriented stamped steel endhead, a motor output shaft projecting from the endhead for coupling to a motor load, and a self-aligning spherical bearing mounted on the endhead for rotatably supporting the shaft. The bearing has a cylindrical extension that projects axially outwardly from the motor case coaxially with the shaft. The bearing extension is constructed and arranged to be engaged by the support structure and/or load coupled to the shaft for locating the same coaxially with the shaft. The bearing, including the extension, is of homogeneously integral unitary construction, preferably of lubricant-impregnated porous metal.
