Precision Rotation Stage, Aperture, Ø159 mm, ±2° Fine Adjustment, Metric

The M-UTR160A Precision Aperture Rotation Stage is ideal for±2° fine-tuning angular orientation of any component after rotating it to an approximate angle. A center aperture permits convenient mounting and adjustment of rotating components in transmissive applications. Cross-roller bearings are preloaded in precision-ground, tool steel races for a smooth, accurate trajectory with minimum eccentricity. Disengaging the side-mounted clutch knob permits continuous 360° free rotation. Once the approximate angular orientation is obtained, a zero-backlash manual drive provides a fine adjustment of 4°. Scale markings and a vernier on the side of the rotation stage measure angular position with 1 arc min resolution.

UTR Rotary Stages mount to UMR Series Linear Stages and other components with BR Series Bridles (set of four are included with each stage), which fit on the mounting collar around the circumference of the base. For mounting UTR stages beneath UMR stages, an adaptor is required. Also, for mounting to other positioners and tables, the optional PBN base plate or BR-U may be used. Stages can also be mounted to components with the tapped mounting holes on the stage’s bottom surface. Components may be mounted to the top of the 159 mm diameter rotation stage via Metric tapped holes. Please refer to the Related Products for possible options.
