Rotary Table RTSA-130
RTSA Series motorized rotation stages provide precision angular positioning accuracy combined with high load
capacity. There are three stage sizes with center aperture from 20 mm to 60 mm available, optimizing load
capacity, torque, speed and resolution for a variety of operating conditions. Tappered roller bearings allow for off center
loads in a reduced footprint. The single monolithic design offers improved stiffness without
compromising dynamic performance. Precise rotation is ensured by bevel gear design with gear reducers to offer multiple
choices of gear ratios. RTSA stages are driven by the stepper motors or servo motors with incremental or abslolute multi-turn encoders.
Rotary tables RTSA Series can be offered in these variants:
without gear reducer
with in-line gear reducer
with 90 degrees right angle reducer
RTSA-130-03 (SHOWN WITHOUT GEAR REDUCER AND WITHOUT MOTOR)
GEAR RATIO 3:1
RTSA-130-GR (SHOWN WITH GEAR REDUCER AND WITHOUT MOTOR)
GEAR RATIO GR = 9, 15, 30)
