Motorized Rotation Stage

MRS Series
0.001 mm Resolution
0.01 mm Positioning Accuracy

MRS series motorized rotation stages are designed and manufactured for automated positioning applications. Since perfectly matched worm gear assembly is used as drive mechanism, play and back-lash is minimal in these stages. 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 with 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, whenever 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 required finish.
