The URS50BPP Rotation Stage provides precision 360° continuous motion in a low profile package. It meets the requirements of numerous research and industrial applications. The high-torque stepper motor provides the highest dynamic speed range and allows for rotating speeds up to 40°/s. All URS rotation stages feature a proprietary 4-point contact ball bearing. The unique, 2-piece design of the URS provides a low-profile compact stage with exceptional stiffness, high reliability and outstanding wobble and eccentricity. The tilted worm screw arrangement allows for 4 symmetric mounting holes as compared to other designs that only feature 2 or 3 mounting holes. This enables the URS stages to provide better support of higher or off-centered loads. Additionally, the flexible preloading system for the worm gear was improved to guarantee a backlash-free operation with an MTBF of 20,000 hours.
