Rail: grooves or ridges or other metal material can withstand, a fixed guide device and the mobile device or an apparatus which reduce friction. Longitudinal grooves or ridges on the surface of the rails for guiding the fixed machine parts, special equipment, and other equipment. Also known as the slide rails, linear guides, linear slides, linear reciprocating motion for the occasion, with a higher rating than the linear bearing load rails, and can assume certain torque linear guide can achieve high precision at high loads linear motion. Linear guide generally used in conjunction with the ball screw The ball screw is rotary motion into linear motion, or linear motion into rotary motion for the desired product. Ball screw by screw, nut and ball composition. Its function is to convert rotary motion into linear motion, which is a further extension and development of ball screw, and the significance of this development is to slide into action from the rolling bearing action. With little friction, ball screws are widely used in various industrial equipment and precision instruments. STAF rails, rails, Shandong by Shandong Fu Fu Chun Chun Machinery Technology Co., Ltd ..
