ABSTRACT:
A pivot mechanism for a rotary actuator in a disc drive data storage device comprising a pivot shaft having a shoulder near one end thereof, the pivot shaft disposed in a central bore of an actuator body having a medially disposed narrow section spatially separating upper and lower bearing assemblies supported on the pivot shaft. Tolerance rings are disposed between the bearing assemblies and the actuator body, and a preloading resilient member biases the bearing assemblies to abut against the narrow section and the shoulder on the pivot shaft. Preferably, adhesive bonds the upper bearing assembly to the pivot shaft once preloading is achieved.
