Abstract
An overhead conveyor includes an I-beam having a web and a pair of side flanges. A pair of opposed interconnected brackets are adapted to support a load, and a trolley wheel assembly is journalled upon each of the brackets and movably mounted upon the I-beam. The wheel assembly comprises a cylindrical shell having an annular shoulder flange at one end and an axial shaft extending from its other end and projected through the upper end of a bracket and secured thereto. A wheel having an axial bore and an internal annular flange has snugly fitted therein a pair of graphite alloy sleeve bearings which bear against the wheel flange, the wheel bearings being loosely disposed upon the shell. The shell flange loosely and retainingly engages one of the bearings and a washer on the shell shaft loosely and retainingly engages the other of the bearings against axial endwise movements respectively.
