GJAIIH Roll Spline Subdimension Series

the precision ground Shaft by balls, the torque is transferred. The spline has compact structure. It can transfer the Over load and motive power. It has longer lifetime. At present the factory manufacture two kinds of spline, namely convex spline and concave spline. Usually the convex spline can take bigger radial load and torque than concave spline. Linear motion rolling spline, has three rails sharing in excircle of spline shaft, balls are running in certain six loading paths formed by bulge outs of the three rails and the respective sections of spline nut.
