Introduction

In mechanical engineering, 'guiding' refers to a mechanism that allows and controls movement in a specific direction. For example, a linear guide enables movement in a straight line.

Linear guides are often used in machines where precision and stability are important. They usually consist of a rail and a carriage that moves along the rail. There are different ways to achieve the right guidance for the specific application. It can be based on sliding properties, ball circulation, or rollers. The choice of guidance depends entirely on the application
