Precision Rotation Stage, DC, Continuous 360° Motion, URS150

The URS150BCC Rotation Stage provides precision 360° continuous motion in a low profile package. It meet the requirements of numerous research and industrial applications and are directly compatible with our XM, GTS, IMS and other series of linear stages. This DC motor version features an ultra-high resolution 8,000 cts/rev rotary encoder with index pulse for precision homing and is the recommended choice for applications requiring accurate bi-directional positioning. For the tightest position control, the rotary encoder is mounted directly on the worm screw. This eliminates most of the possible error sources associated with indirect read feedback devices. The high-torque DC motor provides the highest dynamic speed range and allows for rotating speeds up to 80°/s. It features an adjustable limit switches to prevent over travel. 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.
