Ball Splines
The Ball Spline is a rolling guide spline bearing. This is an innovative product with a ball rolling on a groove connected to the shaft, realizing allowable loads greater than with linear bushing and enabling torque transmission while making linear movements.
Medium Torque
With the medium torque type Ball Spline, the spline shaft has two to three crests on the circumference, and along both sides of each crest, two rows of balls (four or six rows in total) are arranged to hold the crest so that a reasonable preload is applied.
High Torque
With the high torque type Ball Spline, the spline shaft has three crests positioned equidistantly at 120 degree, and along both sides of each crest, two rows of balls (six rows in total) are arranged so as to hold the crest.
