Motorized Heavy Duty Rotation Stage - MRSH Series Print

These are heavy duty stages which can take vertical loads beyond 200 kg’s. Worm and gear assembly perfectly matched to minimize play and back-lash is used as drive mechanism. 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 is used as the electrical actuator and is connected to the worm. Shaft of the stepper motor is connected to a 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 and finished by black anodizing. The stage can be manufactured in stainless steel and mild steel as well with the required finish.
