Lead Screws, Ball Screws & Ball Splines

Lead screws, ball screws, and ball splines are essential mechanical components used in motion control and precision positioning applications across various industries. These components convert rotational motion into linear motion with high accuracy and efficiency, making them ideal for machinery, automation systems, and precision equipment. Lead screws work by utilising a helical thread design, while ball screws incorporate rolling elements (balls) to lessen friction, resulting in smoother and more efficient motion. Ball splines, on the other hand, offer both rotational and linear movement capabilities, making them versatile for applications requiring complex motion. 

Working Principle of Lead Screws, Ball Screws & Ball Splines

• Lead Screws: Utilise a helical thread to convert rotational motion into linear motion, relying on friction between the screw and nut.
• Ball Screws: Feature ball bearings that roll between the screw and nut, reducing friction and improving efficiency and accuracy.
• Ball Splines: Allow for simultaneous rotational and linear movement, using ball bearings to reduce friction.
