The ball spline has load groove of three row on the outside diameter of shaft. Due to the Gothic arch groove design, it could be make sure three grooves withstand clockwise or Counterclockwise of torque at the same time, and then increase the service life and rigidity. The balls recirculation in ball holder, prevent balls falling from the spline nut while assembling.

The Spline nut has a special designed support bearing directly set up on the outer ring of the nuts. The Spline is capable of performing two modes of motions (rotational and linear) with a single shaft by rotating or stopping the spline nut. The rows of balls are held in a special resin retainer incorporated in the spline nut so that they smoothly roll and circulate.
