The RM-3 Series motorized rotary stage is machined from 6061 aluminum alloy to provide a light yet stiff and stable platform.
The design takes advantage of a single preloaded crossed roller bearing for the table movement. This design approach eliminates the use of a dual bearing configuration thus improving on axial runout and wobble. This rotary table utilizes a worm gear drive with available gear ratios of 90:1 and 45:1. The worm gear is preload to minimize the backlash in the gear train.
The RM-3 is available as a vacuum compatible rotary stage. The vacuum compatible version uses a special stepper motor that has all paint and oils removed. The leads from the motor utilizes a Teflon insulation. All aluminum stage parts have a clear iridite finish.
