Spline Nut has a ball retainer which allows for the Spline Nut to be removed and re-applied to the Spline Shaft without the ball elements falling out.There are four precision ground ball grooves on the Spline Shaft providing a guarantee of extremely smooth and accurate movement. The feature of optimum angle for ball contacts provide for idealistic preload which enhances the mechanical rigidity by eliminating radial clearance.
