In the white paper, Demystifying Ball Spline Specs, you’ll learn how the ball spline bushing’s load capacity (including moment load) can be increased by manipulating any of these six factors: Four factors relate to the area of ball contact, i.e., the number of grooves in the shaft, the shape of the grooves, the length of the nut and of its raceways and how close the tolerances are. Five and six are shaft rigidity and mounting systems.
