A2505TS Rotary Table
DISCONTINUED
The A2505TS differs from gear driven Rotary Tables in that these turntables can be spun quickly by hand. Tightening the the clamping knob allows fine motion control.
Anywhere within the 360°, there can be a 12° range of fine (knob controlled) adjustment. The A2505TS is also priced more economically than other rotary stages.
Features
Easy to read engraved 360° scale
6 minute (0.1º) resolution
Maximum horizontal load capacity of 200 pounds (90 kg.)
Rugged black anodized finish
How the Velmex A2505TS Rotary Table works
Unlike other Rotary Tables, the A2505TS does not use a worm and gear design. Instead, they use a spring-loaded tangent screw drive for fine adjustments. With the Lock Knob released, the turntable is freely rotated by hand to the approximate target position.
Turning the Adjust Knob engages a tangent screw driven against a spring-loaded yoke, allowing you to fine tune your position to 0.1 degree. The spring will resist up to 14 oz-in of rotational torque.
Typical applications include mounting and rotation of test specimens, cameras, transducers, sensors, mirrors and other components. These tables cannot be motor-driven, or vertically mounted except for light (< 1 lb.) loads, and are not recommended for strong pulling (tensile) loads.
The Velmex A2505TS Turntable is only manually-operated and cannot be motorized. For motorized rotating tables check out our Rotary Tables.
(Note: Center is not a through hole.)
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.
