Abstract
The specification discloses a preferred system, apparatus, and method for constructing a pivot cartridge assembly. The preferred embodiment of the present invention involves the following steps. A pivot bearing and an actuator assembly are provided. The actuator assembly has an aperture for receiving the pivot bearing. The actuator assembly is heated until the aperture of the actuator assembly expands to accommodate the pivot bearing. The pivot bearing is inserted into the aperture of the heated actuator assembly. When the actuator assembly cools, the aperture of the actuator assembly thermodynamically contracts and constricts around the pivot bearing, locking the bearing in place. As a result, the actuator assembly and pivot bearing behave as a single rigid unit.
