The M-UTR80A Metric 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 79 mm diameter rotation stage via Metric tapped holes. Please refer to the Related Products for possible options.


M-UTR80A度量精密孔径旋转舞台是理想的±2°角定位微调后的任何组件旋转一个近似的角度。中心孔径允许在传输应用中方便地安装和调整旋转部件。十字滚子轴承预装在精密地面，工具钢为一个平稳，准确的轨迹与最小偏心。分离侧式离合器旋钮允许连续自由旋转360°。一旦获得近似角定位,zero-backlash手动驱动提供了一个微调4°。旋转台侧面的刻度和游标以1弧最小分辨率测量角位置。

UTR旋转级安装到UMR系列线性级和其他带有BR系列桥架的部件(每级包括四组)，安装在底座周围的安装环上。在UMR级下安装UTR级需要一个适配器。此外，对于安装到其他定位器和工作台，可使用可选的PBN基板或BR-U。级也可以安装到组件与抽头安装孔在级的底部表面。组件可以通过公制抽头孔安装到直径79毫米旋转级的顶部。请参考相关产品的可能选项。
