Motorized Heavy Duty

Rotation Stages

MRSH Series
0.001 mm Resolution
0.01 mm Positioning Accuracy

These are heavy duty stages which can take axial loads beyond 200 kg’s. Perfectly matched worm and gear assembly to minimize play and back-lash. The top rotating part which is plane in this case, is provided with rotary graduations on the periphery throughout 360 degree.

Radial play is eliminated by the use of preloaded thrust bearings using balls as rolling elements. Stepper motor which is connected to the worm is used as a electrical actuator. Shaft of the stepper motor is connected to the rotating knob as well for manual adjustments, when ever required. Top surface of the stage is provided with tapped holes and base with counter bored holes for mounting. Standard stages are manufactured in aluminium alloy with black anodizing finish. The stage can be manufactured in stainless steel and mild steel as well with the required finish.

To meet the most critical positioning demands, rotary encoder is used.It converts the angular position of a shaft to digital code, making it an angle transducer.
