Abstract:
An example hinge includes a hinge pin extending along an axis and a first knuckle for receiving the hinge pin. The first knuckle is rotatable about the axis. A second knuckle for receiving the hinge pin and is rotatable about the axis. At least one bearing limits relative rotation between the first hinge knuckle and the hinge pin. The example hinge assembly may include a tolerance ring between the hinge pin and the first knuckle to urge the bearing away from the axis. An example method of producing a hinge includes the steps of permitting a first hinge plate to move relative a hinge pin and limiting movement of a second hinge plate relative a hinge pin. The method biases a bearing adjacent the hinge pin to limit movement of the second hinge plate relative the hinge pin.
