Ball cage universal joints, commonly known as constant velocity (CV) joints, use a set of precision steel balls running in curved grooves between inner and outer races, retained by a cage. This design delivers true constant velocity rotation regardless of operating angle, eliminating speed fluctuations inherent in cross-type joints. Essential for modern front-wheel and all-wheel drive vehicle axles, these joints also serve high-speed industrial machinery and robotic arms where smooth, vibration-free power transmission is critical.
