An actuator assembly having a plurality of head suspensions removably secured to a spindle of the actuator assembly. Each head suspension is mounted to an arm, which is mounted to an actuator spindle through the use of a spacer having an annular lip. A spacer having an aperture is coupled to the actuator spindle by inserting the spindle through the aperture of the spacer. The actuator arm includes a pair of spring arms that can be expanded from a neutral state to a stressed state to engage an annular lip on the spacer for removably securing the arm to the spacer. A stacked array of arms can be formed on the actuator spindle by arranging a desired number of spacers on the spindle and mounting the arms to the spacers. In one embodiment, the spacer includes a single annular lip extending from a first planar surface of the spacer. In a second embodiment, the spacer includes an annular lip that extends from each of a pair of opposite planar surfaces, and an arm is attached to each of the lips. The lips can include a detent in a perimeter edge of the lip that is engaged by a proximal tip of one of the spring arms of the actuator arm. The spacer can also include a guide slot located in the planar surface of the spacer from which the lip extends, with the guide slot being engaged by a boss tower on the arm to properly orient the arm on the spacer when mounting the arm to the spacer.
