ABSTRACT:
A disk head suspension assembly in which a swage ring (a cylindrical hub) is used for attaching a load beam to a head actuator arm. The swage ring is used instead of a typical base plate. A head suspension assembly includes a cylindrical hub having an inner diameter and an outer diameter and a load beam having a load beam hole therein. The load beam hole has a diameter that is less than the outer diameter of the swage ring and greater than the inner diameter of the swage ring. The swage ring is placed concentric with the load beam hole and a series of welds around a periphery of the load beam hole are made so that the welds affix the swage ring to the load beam. The swage ring is inserted into an actuator arm boss hole and the swage ring is swaged outward to create a press fit upon the actuator boss hole.
