Hollow Rotary Actuators Are RoHS Compliant
The DG 200 hollow rotary actuators are RoHS compliant. The larger DG 200 has a repetitive position accuracy of 15 arc-seconds and a total backlash of 2 arc-minutes due to its integrated high rigidity cross-roller bearing structure. A hollow through hole of sufficiently large diameter helps reduce the complexity of wiring and piping, thus further simplifying the equipment design. It has a frame size of 7.87 inches with an internal hollow diameter of 3.94 inches. It develops 440 lb-in (50 Nm) of torque at a speed of up to 110 rpm available for positioning larger inertial loads. A number of selectable accessories are available. Equipment tables and arms can be installed on the output table. This saves one the hassle and cost of designing an installation mechanism, arranging necessary parts, adjusting the belt tensions, etc., when mechanical parts such as belt and pulley are used for installation.
