First, the axial clearance is 0--because the ball spline is an angular contact structure with no invalid stroke in the direction of rotation, so high-precision positioning is possible.

Second, lightweight, compact body structure - can achieve high precision and small size design.

Third, the nut is light in weight and the inertial force is small - the height of the nut and the supporting bearing are responsive.

Fourth, the noise is low and the movement is smooth--Because the ball screw adopts the end cover circulation mode, the noise is low, and smooth and smooth motion can be realized.
