Model DIR Standard-Lead Rotary-Nut Ball Screw is a rotary-nut ball screw that has a structure where a simple-nut ball screw is integrated with a support bearing.

Balls travel along the groove of the deflector mounted in the ball screw nut to the adjacent raceway, and then circulate back to the loaded area to complete an infinite rolling motion.
