1. A gear, comprising:
a metallic gear hub consisting of a monolithic gear core having an axis of rotation and metallic gear teeth that have roll, pitch and yaw axes and are smaller than a final gear teeth size of the gear;
wherein the metallic gear teeth are not co-planar with each other such that at least some of the metallic gear teeth are offset from each other;
a polymer layer on the metallic gear teeth to form polymer gear teeth on the metallic gear teeth, wherein the polymer gear teeth comprise the final gear teeth size of the gear, such that the metallic gear hub is configured to fully support a contact line of a mating gear; and
the metallic gear teeth comprise overhangs that extend in opposite axial directions, and an overhang outer axial dimension between opposite ones of the overhangs exceed a hub outer axial dimension of the metallic gear hub.
