Ball Screw Jack (RNK-0.5 TON~20 TON) offers ball screw jack use the same worm gear set arrangement as acme screw jack. The additional of a high efficiency ball screw and nut reducers the required input torque to approximately one-third the torque required for the acme screw jacks. * High speed, high accuracy, high efficiency, high frequently, light load, long life and low noise. * All versions are designed for both tensile and compressive loads and will operate

Ball screw assembly is consisted of screw, nut and balls. It is to transfer the rotary motion into linear motion or transfer the linear motion into rotary motion. Ball screw is widely used for all kinds of industrial equipments and precision instruments. Especially in recent years, it is widely used in CNC machine tools. Yigong ball screw is made by grinding and whirling, not rolled, and it has two kinds of ball screw P for positioning and T for transmission,
