Abstract
A method of producing a replaceable one piece annular outer race having an axial bore, an uninterrupted inner annular concave raceway facing into the bore and an outer surface. The method comprises the steps of applying an overlayment of filaments onto a cylindrical axially split mold assembly to form a one piece outer race substrate. The mold assembly includes first and second separable semi-cylindrical mold halves each having a semi-cylindrical convex outer mold surface, a mounting bore extending axially through the mold assembly, a removal axis normal to the mounting bore axis and a support removably mounted in the mold assembly mounting bore. A coat of hardenable liquid resin is applied to penetrate the filament overlayment substrate, after which the coated substrate is cured to form a hardened one piece outer race on the mold assembly. The cylindrical mold halves are removed from the hardened outer race to yield a single piece annular outer race. The support is removed axially from the mold mounting bore.
