Abstract
An aerospace actuator is provided and includes an actuator housing, second and third parts respectively including retraction-limiting and extension-limiting surfaces, a piston and a stroke limiting device. The piston is movable within the actuator housing between a retraction-limited position where the piston impinges against the retraction-limiting surface and an extension-limited position where the piston impinges against the extension-limiting surface. The stroke limiting device includes at least one of a first adjustable engagement unit and a second adjustable engagement unit. The first adjustable engagement unit is disposed between the actuator housing and the second part for adjusting a first distance between the actuator housing and the retraction-limiting surface. The second adjustable engagement unit is disposed between the second part and the third part for adjusting a second distance between the extension-limiting surface and the retraction-limiting surface.
