RB-90 Large Aperture Rotary Stage


The RB-90 Series rotary stage offers high speed rotation with a large 90 mm aperture.

RB-90 Belt Driven Rotary StageThe design takes advantage of a single 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. The RB-90 utilizes a timing belt to couple the motor to the spindle, eliminating backlash.

 

The RB rotary stage is available with a 2 phase stepper motor or an MDrive stepper motor with integrated controller.

The motor can be installed from the top or bottom of the rotary stage to give clearance for large diameter payloads.
