Miniature Ball Screws | Turn rotary motion into linear motion

Miniature Ball Screws are a very efficient (90-98%) way to translate rotary motion into linear motion versus lead screws that are typically less than 50% efficient. These high efficiency miniature metric precision ball screws are a very cost-effective solution for use in small or compact spaces. Ideal application are in medical devices, laboratory automation, and semiconduction equipment.

Ball Screw-Dongguan Toco Transmission Machinery Co.,Ltd

Smooth Operation The high efficiency of ball screws is vastly superior to conventional screws. The torque required is less than 30%. Linear motion can be easily changed from rotary motion. High Rigidity and Preload When axial play is minimized in conventional screw-nut assemblies, the actuating torque becomes excessive and the operation is not ...

How to Size and Select Ball Screws: An Engineer's Guide

Ball recirculation inside the ball nut can affect precision and repeatability. As a result, ball nuts are available with a range of pre-load options to reduce or remove the axial play as they rotate around the screw. This allows for better repeatability, for example, because no motion is lost from the clearance in the balls as they reengage.
