Construction and Feature:
The ball spline is an innovative linear motion system,in that balls accommodated in the spline nut transmit torque while linearly moving on precision ground raceways on a spline shaft.Furthermore,one significant difference against the usual ball bush is that a single spline nut can exert preload.As a result of this ability,the ball spline is well suited for use under severe service conditions involving vibration and the application of impact loads,and in locations that require highly precise positioning and high-speed operation.The ball spline has two loading ball rows to be arranged so that ball rows in the 2 grooves at 180。To be precisely ground
