Vacuum Compatible Precision Rotation Stage, Stepper, URS50

The URS50BPPV6 Vacuum Compatible Rotation Stage provides precision 360° continuous motion in a low profile package. This version can be controlled with the motor mounted encoder and also in open loop. The stepper motor is directly attached to the worm screw using a proprietary bellows coupling that has a high torsional stiffness and is capable of rotation speeds up to 4°/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, 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 guarantees a backlash-free operation with an MTBF of 20,000 hours.

Note: The cable supplied with the stage is not vacuum compatible due to various feed-through configurations and customer preferences. Please contact Newport for vacuum compatible cable options.
