Spline structure: the ball spline is composed of a spline shaft and a spline sleeve. The circulating ball in the spline sleeve moves in a straight line while driving the spline sleeve to rotate in the groove of the precisely ground spline shaft;

Pre pressing grade: precision ball spline can adapt to special working conditions such as vibration, impact load, high-precision positioning, high-speed movement, etc. by applying different pre pressing to a single spline sleeve;

Replacement and high precision pursuit: the ball spline can be used as an ordinary linear bearing. Its rated load is more than ten times that of ordinary linear bearings, so it can be designed into a very small volume. It can be safely used even under the cantilever load and impact force, and its service life is very long. It has high precision, good stability, exquisite design and space saving;

Field of application: The ball spline is widely used in industrial robot mechanical arms, medical devices, automatic handling machines, grinding machine spindle drive shafts, various speed changing devices, precision indexing shafts, riveting machines, winding machines, conveyors and other high-precision equipment. It is a highly reliable linear motion system;
