Load 200 Kg

RTGA Series motorized rotation stages provide precision angular positioning accuracy combined with high load
capacity. There are three stage sizes with center aperture from 32 mm to 100 mm available, optimizing load
capacity, torque, speed and resolution for a variety of operating conditions. Cross-roller bearings allow for offcenter
loads in a reduced footprint. The single monolithic design offers improved stiffness without
compromising dynamic performance. Precise rotation is ensured by gear/pinion mechanism. RTGA stages are
driven by the open loop stepper motors or closed loop servo-step motor with programmable resolutions to
provide sub arc-sec angular resolution.
