This Ball Spline has no angular backlash to increase the rigidity by providing a preload with one spline nut since the spline shaft has 3 crests equidistantly arranged at 120 degrees on the circumference, each held by 2 rows (6 rows in total) of balls under a load .

This Ball Spline has a large load capacity in the radial and torque directions since the spline shaft has 2 to 3 crests on the circumference, each held by 2 rows (4 or 6 rows in total) of balls under a load in order to reasonably provide a preload.

This model is a unit type that has gear teeth on the flange circumference, and radial and thrust needle bearings compactly integrated on the spline nut. This Ball Spline is optimal for a torque transmission mechanism with spline nut drive.

This model is a compact unit type of Ball Spline whose support bearings are directly integrated with the outer surface of the spline nut.
