A linear guide system which is used for highly precise control of a linear position applicable in display devices, semiconductors, robots, machine tools, and the entire measurement and precision instruments industry, and more specifically, an adjustable preload type linear guide system, wherein a base member and a slide member are slidably connected with each other for linear motion, and a linear motion actuator, such as a ball screw, a hydraulic cylinder, and a linear motor, is disposed between the base member and the slide member, thereby enabling the slide member to move linearly relative to the base member. The adjustable preload type linear guide system includes: a base member having a base body, and a pair of base rails which are disposed in parallel to each other on the base body; a slide member having a slide body, and a pair of slide rails which are disposed on the slide body to face the pair of base rails, wherein the slide rails slide relative to the base rails by a ball bearing which is installed between the base rails and the slide rails, thereby enabling the slide member to slide relative to the base member; and a preload adjustment unit which is installed between one of the slide rails and the slide body for adjusting the intervals and angles of the slide rails with respect to the slide body, thereby adjusting the preload of the ball bearing which is disposed between the base rails and the slide rails. |
