Ball spline
The design of Ball spline is to utilize the friction force through the contact of steel balls within in the Spline Nut and the grooves on the Spline Shaft. The concept is optimal for the application involve with high speed, vibrates, impacts of loading and precise positioning requirements. Also when the Ball spline is used to function as linear bushing, the Ball spline provides ten times loading capacity than the linear bushing in the like dimensioned but with a compact profile.
