A48 Series Manual Rotary Stages
Manually operated 5″ Ball Bearing Rotary Stage for loads up to 200 lbs.
Velmex Rotating Stages deliver precise, continuous rotating motion for scanning, assembly, testing and production. They are a convenient, accurate method of quickly positioning or rotating a payload vertically or horizontally.
The A48 Series Manual Rotary Stages use a rugged worm and gear drive design with a central rotating ball bearing to turn the payload. These rotary tables can handle 200 lbs. (90 kg.) horizontally and 25 lbs. (11.3 kg.) vertically.
Manually-operated Velmex A48 Series Rotary Stagescan be easily converted to motorized positioners. Simply remove the knob and shaft and attach a stepper motor. The A48 Series is also available as a B48 Series Motorized Rotary Stage.
The A48/B48 models and the A59/B59 series of Rotary Tables have a hollow spindle or open aperture in the center for optical applications.
Specifications
Factors such as size of the motor, size of the payload, travel distance, mounting direction/plane, etc. effect the actual capability of any assembly. Please contact Velmex Application Engineers to configure a system that will meet your exact requirements.
