RTR Roller Bearing Motorised Rotary Stages from Dover Motion RTR Roller Bearing Motorised Rotary Stages from Dover Motion

 Dover’s RTR Series motorized rotary stage incorporates stiff crossed roller bearings and a precision worm gear drive.The 4”, 6″, 8″, 10″, and 12″ diameter rotary stage versions include a preloaded, anti-backlash drive assembly to provide exceptional angular accuracy and repeatability.There is a standard internally mounted Hall-effect reference sensor that is wired directly to a locking sensor / encoder connector for homing position registration accurate to a single step.

The motorized rotary stage includes a stepper motor with a knob and a flexible coupling.A second sensor can also be installed to electrically restrict rotary table travel in applications where the full rotational travel needs to be limited to a specific angle of travel less than 360 degrees.Clear apertures (or through hole) are optionally available in different diameters.Our integral rotary encoder can be specified with our RTR Series rotary stage, where it provides 0.001 degree resolution encoder feedback when combined with a 180:1 worm gear ratio, 200 step per rev. stepper motor and a divide- by-ten micro-step drive.For increased rotary motion resolution, 400 count stepper motor or rotary servo motor are available.


  • High load capacity stiff crossed roller bearings
  • 4" to 12" diameter versions
