Abstract

An opposed conical elastomeric bearing assembly includes a first conical elastomeric bearing with a first inner race and a first outer race, and a second conical elastomeric bearing with a second inner race and a second outer race. Assembling the opposed conical elastomeric bearing assembly may include positioning an outer surface of the second outer race in contact with an inner surface of the first outer race. Assembling the opposed conical elastomeric bearing assembly further includes applying an axial force to urge the first conical elastomeric bearing and the second conical elastomeric bearing together such that a leading edge of the second inner race contacts a shoulder of the first inner race, and, while applying the axial force, deforming a projecting portion of the first inner race such that an outer diameter of the projecting portion is expanded to frictionally engage an inner surface of the second inner race.
