This high capacity rotary stage features a 200mm diameter stainless steel table top designed to support a 700 lb load.
The high-performance rotary stage design takes advantage of a single high capacity preloaded crossed roller bearing for the table movement. This design approach eliminates the use of a dual bearing configuration thus improving on axial runout and wobble. It can be fitted with a high performance servo motor or with a stepper motor. The RM-8 utilizes a worm gear drive with a gear ratio of 80:1. The worm gear is preload to minimize the backlash in the gear train.
Low temperature version available, -50°C to 70°C.
Other Rotation Stage
Also available in Low profile rotary stage and manual rotary stage.
