How the Velmex A59 Series Manual Rotary Tables work
Velmex Rotating Tables 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.
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.
