 The ball screw, also known as a ball screw nut, to be completed by the rotary motion and linear motion conversion to this new drive constructed in the widespread use of CNC machine tools. The structural c haracteristics is equipped with a ball as an intermediate transmission elements in the spiral groove of the screw nut to reduce friction screw and nut are processed on the arc-shaped helical groove, the two arc-shaped helical groove together form a spiral raceway.angular contact ball bearing
 Ball in the interior of the raceway, when the relative motion of the screw and nut, the ball rolling forward along the spiral groove, fundamental for the rolling friction between the screw and nut. Roll out in order to avoid the ball from the nut, the both ends of the spiral groove of the nut with a return to guide the installation, so that the ball can cycle activities.china ball bearing
 The scope of the use of the ball screw pair is extended from time to time, such as aerospace, small fine test installation, electronic instrumentation, and semiconduc tor installation needs miniature ball screw pair. CNC machine tools, machining centers, industrial robots and mechatronics automatic mechanical needs of large lead ball screw pair, in order to meet the feed drive speed from time to time progress.double row ball bearing
