Ball screws

Ball screw linear actuators from norelem are mostly used in machine tool construction. A typical example is the feed and rapid traverse on lathes and milling machines where a rotation is converted into a linear movement to position tools and workpieces.

In contrast to other screw drives where the flanks glide over each other, ball screw linear actuator have the advantage that much less friction is produced, leading to lower drive power and much higher linear speeds. They have much less wear and a higher positioning precision.
