ServoRing rotary tables provide superior angular positioning and are designed to eliminate backlash, friction and wear problems associated with worm, gear and belt drives. Low maintenance and high throughput characteristics of the ServoRing Stage yields the lowest total cost of ownership

Compact package and superior design of the ServoRing rotary stages was optimized to provide highest torque density in the smallest volume. ServoRing stage has clear center aperture that can be used for air or wire line feed-through or beam delivery

To maximize positioning performance ServoRing rotary tables utilizes direct drive three phase segmented brush-less motor technology which allows to optimize torque-speed performance of the stage. "Lo-Cog” magnetic design assures smooth rotation and dynamic performance.

Accurate Positioning performance is assured with precision encoder that provides sub arc-sec positioning resolution. The motor and rotary encoders are directly coupled to eliminate coupling backlash.

Precision cross-roller bearing for combined axial and radial loads are used to maximize performance with respect to wobble and moment stiffness
