Abstract: A lens actuator module includes a lens assembly with an optical centerline and a clear aperture, a bearing guide integrated adjacent to the clear aperture with the centerline of motion substantially parallel to the optical centerline, a linear actuator with a preloaded frictional contact point that moves the lens along the centerline. The preload force is perpendicular to the optical centerline, constant and generated in-line with the contact point such that the preload force produces substantially zero additional friction in the bearing guide irrespective of the location along the optical centerline.
