RTSN-450-250 motorized rotation stages provide precision angular positioning accuracy combined with high load
capacity center aperture 250 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. RTSN 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.
