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

Pre pressure level: Precision ball spline can adapt to special working conditions such as vibration, impact load, high-precision positioning, high-speed motion, etc. by applying different pre pressures to individual spline sleeves;

Alternative use, pursuit of high precision: Ball splines can be used as ordinary linear bearings, with a rated load more than ten times that of ordinary linear bearings, so they can be designed with a very small volume, even under cantilever loads and impact forces, and can be safely used with a long service life. It has high precision, good stability, exquisite design, and saves space;

Application areas: Ball splines are widely used in high-precision equipment such as industrial robot arms, medical equipment, automatic loading and unloading conveyors, grinding machine spindle drive shafts, various transmission devices, precision indexing shafts, riveting machines, winding machines, conveyors, etc. They are highly reliable linear motion systems;
