Among linear bearings, and can be divided into many sub-classification of joint bearing processing, linear bearings specifically what you classify it? We take a look at: linear bearings linear bearings into metal and plastic linear bearing metal, metal linear bearing is a bearing joints linear motion system supplier selling low-cost production, for unlimited travel with the cylinder axis. Since the ball bearing and the shaft was the point contact, so the use of the load is small. Minimal friction ball rotation, which can obtain high precision smooth movement. The ball screw is the rotary motion into linear motion, or linear motion into rotary motion of the desired product. Ball joints are transmission components and precision machinery and machine tools most commonly used bearing customized, its main function is to convert rotary motion into linear motion, or to convert torque into axial forces repeatedly, while both high-precision, reversible and high efficiency. With little friction, ball screws are widely used in various industrial equipment and precision instruments.
