Compact Linear Actuators

The DRLII Series features a structure in which the rotor is hollowed out and the ball screw is stored inside. The rotation of the hollow rotor rotates the ball screw nut and by setting up an anti-spin mechanism* on the tip of the ball screw, the ball screw shaft is moved in a linear manner.

There are two types of ball screws: the ground ball screw for fine feed and high-precision positioning and the rolled ball screw which is reliable for ordinary positioning.

Because the ball screw shaft is stored in the hollow rotor section, the maximum stroke is secured with the shortest overall length. Also, a large bore bearing is positioned on the outer circumference of the ball screw nut in order to directly receive the large thrust loads generated in linear motion.
