Difference Between Ball Screw and Linear Guide

Ball screws and linear guides and are very different. Although they are both linear motion, their working principles, requirements and scope of use are different, but both perform very well in linear transmission.
Ball screw is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion, or convert torque into axial repetitive force, and it has the characteristics of high precision, reversibility and high efficiency. It is mainly used in some large-scale machine tools, engraving machinery, etc. It is very convenient to convert the rotary motion into linear motion, which is very convenient to use, thereby reducing the wear and tear of the entire equipment in terms of rotation.

Linear guides are widely used, but there are many types. Square four-row high-ball guides are used in some large machine tools, such as surface grinders, slicers, wire cutting, etc.; For precision measuring instruments, semiconductor manufacturing and inspection equipment, non-standard automation machinery and other applications where precision linear motion is important, it is also crucial to select the correct guide rail for different equipment.
