A non-metallic bearing (10) is comprised of a fiberglass reinforced elastomer, preferably a rubber matrix (22), inner portion, or bearing blank (11), and a fiberglass reinforced plastic, preferably an epoxy matrix (33), outer portion, or shell (12). A piece (20) having predetermined dimensions is cut from a sheet (16) of fabric (14) loosely woven from reinforcing glass cords. The piece (20) is bent into a hoop (13) and inserted into a mold casing (21). An elastomer chosen to form the matrix (22) of the bearing blank (11) is injected into the mold casing (21) and cured. The bearing blank (11) is pressed from the mold casing (21) and mounted on a mandrel (25). As the mandrel (25) is rotated a woven reinforcing fabric (26) is wound onto the outer periphery of the bearing blank (11). The fabric (26) is impregnated with a plastic resin chosen to constitute the matrix (33) of the outer shell ( 12). When the resin is cured the bearing (10) may be removed from the mandrel and the outer shell (12) may be machined to the desired outer diameter.
