LM type linear ball bushing and LM type cylindrical shaft comprise the linear motion system which can be used to to complete the infinite linear motion. The contact way is point contact between steel balls and LM shaft. It allows smaller load, but can achieve high precision and light linear motion in the minimum friction. Linear bushings are widely used in office equipment and its peripheral equipment, various measuring instruments, automatic recording device and digital three-dimensional measuring instrument / multi-axis drilling machine, punching and tool grinding machine, automatic gas cutting equipment, printing machinery, Card machines and food packaging machines and so on.
