ABSTRACT:
A disk drive includes a pivot bearing and actuator arm. The actuator arm includes a stepped pivot bearing housing. The pivot bearing housing has a first nominal inside diameter and a relatively smaller second nominal inside diameter to align the pivot bearing within the bearing housing. The pivot bearing has a body and a head. The head press-fits within the first inside diameter and the body press-fits within the second inside diameter to align the bearing assembly in the bearing housing. The body diameter of the bearing assembly is smaller than the bearing housing first nominal diameter to enable the bearing housing to pre-align the bearing assembly with respect to the bearing housing.
