1 Ball Spline

2 Feature / HIWIN Ball Spline is a rolling guide element, mainly composed of nuts, screws, steel balls and retainers. By the steel ball between the nut and the screw, the rolling of the infinite cycles allows the nut to move linearly along the screw with high precision. The ball contact point in ball spline is angular contact structure, which can withstand both radial and torque load. With the integrated design between nuts and bearings, it makes the ball spline achieve high payload with compact structure. The ball spline has three sets of loaded balls, where the balls are under face-to-face angular contact and held by the retainer. The optimized retainer design provides the high speed, acceleration and deceleration guiding movement as well as hold the balls firmly without falloff when taking out the shaft. Transmission of torque Compared with the linear bearing, the balls rolling on the groove with the angular contact offer the relative movement between the nut and the screw in order to achieve the function of the torque transmission. Integral structure With the integration of the nut and support bearings, the ball spline can achieve high precision and the compact structure design. Easy installation With the optimized retainer design, the spline shaft can easily be removed without having the balls falloff from the nut. Lubricant path With the optimization of the lubricant path, the grease will be directly guided to the ball track to improve the lubrication effect and enhance the service life.
