Abstract

Embodiments of the present invention describe the arrangement of bearings in actuators. In particular, the bearings are fit into a surface of the actuation member instead of into the housing for the actuation member. In an exemplary embodiment of a rotary vane actuator, the bearings are fit into the axial surfaces of the vane actuation member instead of in the floor and rotor cap of the housing. In this way, the problem of an axial bearing working loose and grinding a leak path into the actuation member is addressed.
