The small size allows use in confined spaces, such as laser cavities, disk texturing machines, or manufacturing areas for fiber optical components. The lightweight, low profile design incorporates an aluminum body with pre-loaded ball bearings. This proprietary ball bearing design provides smooth rotation with minimal wobble. A precision ground worm gear produces consistent driving torque to the rotating carriage and eliminates variations in motor current. The motor is folded inside the stage body to give an extremely small footprint for a stage at this level of precision. Note Due to its very low profile, the PR50 and SR50 stages contain pressure sensitive components. For use at a pressure level below 0.25 bar, please contact our sales department.

The stages are equipped with a hardware origin allowing the stage to return to a reference home position to within 0.01°. SR50 stages can run in continuous rotation mode. The PR50 stages are a cost-efficient alternative to the SR50 for applications that do not require the high-resolution and precision of the SR50, or for applications that could benefit from higher speeds up to 20°/s. The PR50 stages feature angular resolution of 0.01°, which may be achieved with either DC Servo or open-loop stepper motors in half-step mode. The stages are equipped with a hardware origin and allow for continuous rotation of 360°. Phone: 1-800-222-6440 • Fax: 1-949-253-1680
