360 Degree Continuous Rotation Stages

360 Degree Continuous Rotation Stages

  • Continuous 360 degree rotation
  • Fine pitch worm screw driven for high precision
  • Lockable
  • Four convenient sizes to suit most applications

 

These unique rotation stages provide continuous high precision 360 degree rotation control. The precision rotary action is driven by a fine pitch screw and worm gear to provide fine positioning resolution. And a locking mechanism ensures that the stage is stable and will not move after the desired position is obtained. The continuous rotation stages are available in 120, 65, 40 and 25mm footprints. All stages have central apertures and may be mounted with an optical beam passing through its center. Each stage has hole patterns suitable for use with other OptoSigma linear and rotation stages. 120, 65 and 40mm models are available with inch or metric hole patterns. The 25mm stage is offered only with metric holes. Please refer to the provided CAD drawings for specific stage sizes and hole pattern configurations.

Rotation Stages

Rotation Stages

  • Continuous 360 degree rotation
  • Fine adjustment by micrometer
  • Concentricity <50microns
  • Compatible with linear translation stages
  • Five sizes cover most applications
  • Inch and metric mounting

 

Rotation stages permit the precise angular adjustment of components. These stages use plain brass bearings to provide coarse adjustment over a full 360 degree circle. A scale around the circumference provides an indication of the angle. Once set approximately in place the stage may be locked by means of a clamp screw and then fine adjusted by a micrometer (fine pitch screw is used for the 25mm stage). The sizes of these stages are such that they may be mounted together with translation stages to form compound motion devices. The largest stage we offer has a diameter of 160mm and a 102mm central aperture. The 120mm stage has a 62mm central aperture so it can be mounted with an optical beam passing through its center. The 90mm stage will accept a 65mm linear stage and the 65mm rotation stage can be mounted on top of a 65mm translation stage. The 40mm stage is ideal for OEM applications. The 160, 120 and 90mm stages utilize crossed roller bearings for high load capacity.
