Abstract
A method of making a split bearing sleeve having flanges at the opposed ends thereof for mounting a sprocket wheel on an axially extending shaft is disclosed herein. The method includes the steps of providing a mold having axially aligned recessed areas for the flanges and an intermediate area extending between the recessed areas for the flanges, placing a thin strip of polyethylene in the intermediate axially extending area such that the strip extends partially into the recessed flange areas, and pouring heated polyurethane into the mold to fill the recessed areas for the flanges and the intermediate axially extending area to encapsulate the thin strip in the recessed flange areas.
