Exemplary embodiments disclosed herein include bearings with three races: an inner race, a shared race, and an outer race that exhibit increased life under oscillatory loads. The exemplary embodiments may include one or more directional biasing mechanisms configured such that when a bearing shaft rotates in one direction, the shared race rotates with it, and when the shaft oscillates in the other direction, the shared race is impeded from moving in the other direction. Under continued oscillation, the shared race will “walk” in circles around the shaft, effectively distributing the load and wear over the entire circumference of a bearing surface.
