Ball screw type
The rotary stage uses the ball screws. It is the best for driving a micro angle.

*High durability*
Backlash made by attrition as continued the minute motion in worm gear type was cancelled.
Durability will be improved to motion mechanism changes from worm gear to ball screw.

*Improvement of the acceleration/deceleration*
As frection (sliding residence) is small as compared with worm gear, it can be set up and accelerated smoothly.

*Reduced backlash*
It will be almost no backlash using pressurized parts for the mechanical elements.

Motion mechanism: Ball screws φ6 lead 1mm
Motion guide: Combined angular bearing

Table size (mm): φ40、60
