The ultra-minature ball screws are available in diameters as small as 3 millimeter with a choice of two pitches – 1 millimeter or 0.5 millimeter. 

Steinmeyer offers miniature screws from 16 millimeter diameter (with up to 30 millimeter pitch), down to the 3 millimeter diameter. The ball screws are equipped with one of four types of ball nuts (cylindrical, flange, etc.), with or without preload. They are available with journals machined to a control drawing.

These ultra-miniature ball screws are manufactured from standard tool steel (52100), hardened and then precision-ground to meet ISO tolerances from P0 to P5. Stainless steel material is available as an option. The ball screws provide precision linear drive mechanism for a variety of medical devices. Because ball screws offer higher efficiency compared to lead screws, they require smaller and thus lower power motors. This saves battery life on portable devices and also means lower heating and longer life.
