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.
Pre loaded rolling contact bearings are used to minimize friction and to eliminate play
Driven by precision worm gear assembly
Graduated rotary scales are provided for visual reference of positions
Can be fitted to our motorized linear stages for multi axis configurations
Custom stages can be constructed out of aluminium, steel and SS depending on the application
Holmarc can provide custom mounting pattern on request
