Abstract
A method for making a dual actuator pivot, wherein the need for adhesive bonding is eliminated and assembly time is minimized. An upper sleeve assembly includes an upper and lower ball bearing press fitted therein and a lower sleeve assembly includes an upper ball bearing press fitted therein, the first and second sleeve assemblies being press fitted to a shaft having a ball bearing press fitted at the base of the shaft. A predetermined axial load that is tuned to select a desired resonance frequency for the first and second actuator bearing assemblies may be applied during the press fitting of the first and second sleeve assemblies. The shaft may be chilled to shrink the shaft. Alternatively, the components may be heated.
