ABSTRACT:
A missile fin control actuator includes a housing having a hollow cavity within which is mounted a single bearing. On the inner race of the bearing, a lower cap attaches the base of a fin mounting shaft or integral fin for rotation with the inner race. The outer race of the bearing is retained in a fixed position in the housing by an upper cap. A crankarm attached to the lower cap may be actuated to rotate the lower cap and the inner race and mounting shaft (or integral fin) therewith.
