Abstract: A bearing friction testing apparatus includes a bearing support structure having a support arm with a bearing mount for mounting a test bearing with a bi-directional load support ring for attachment to the bearing race with a pendulum attachable to the support ring for adding one direction of force and a tension line attached to the ring for applying a second direction of force transverse to the first direction of force with a pendulum latching device for latching the pendulum in a loaded position and releasing the pendulum with a measuring instrument for measuring the rate of decay in the amplitude of oscillation of the pendulum.
