The rotary ball spline is a high-efficiency transmission component that integrates rotational and linear motion functions, composed of a spline shaft, balls, and a spline sleeve. By allowing the balls to roll within the raceways, it converts sliding friction into rolling friction, enabling simultaneous high-precision transmission of rotational and linear motions. These ball splines are widely applied in equipment, such as CNC machine tools, industrial robots, and automated production lines.
