Ball Screw & Guide Screw for Precision Linear Motion Systems

The Guide Screw, commonly known as a Ball Screw or Ballscrew, is a high-efficiency mechanical component that converts rotary motion into precise linear motion. It consists of a threaded screw shaft, a ball nut, and recirculating steel balls that roll between the nut and the screw, delivering extremely low friction, high transmission efficiency (up to 90%), excellent positioning accuracy, and long service life.

Compared to traditional lead screws or acme screws, Guide Screw (Ball Screw) offers significantly lower backlash, higher speed capability, and better rigidity, making it the preferred choice for modern precision equipment. It is frequently paired with Linear Guide Rail Slider to create complete, high-performance linear motion systems.
