Ball screw type

KGB/KABseries

High precision stage with the ball screws. It is the best for driving a micro angle.


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.


As frection (sliding residence) is small as compared with worm gear, it can be set up and accelerated smoothly.


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

Motion mechanism: Ball screws φ6 lead 1mm
Motion guide: Crossed roller guide
Sensor logic option:
Selectable sensor logic from 3 types depending on your specification. (Only for table size 70 x 70mm.)

Table size (mm): φ40、60
