Ball Splines, developed by THK, are revolutionary linear motion guides that enable both rotary and linear motion on a single shaft. These splines feature an innovative design where balls roll along an R-shaped groove machined into the spline axle. Precision Ball Splines come with flanged or non-flanged nuts, making them ideal for high-precision, multi-axis motion applications. They offer smooth movement, precise positioning, and high reliability. Additionally, Heavy Duty Ball Splines, available with or without keyways, handle high torsional loads while providing anti-friction linear motion at high speeds. These robust and dependable components find applications in robotics, CNC machines, precision machinery, and other industrial settings where precise positioning and durability are critical .
