Gear spline shaft is determined by its excellent characteristics of the following aspects: high transmission efficiency, high positioning accuracy, transmission reversibility, long service life, good synchronization performance, excellent price, fast delivery time.

The gear spline shaft the origin of the name is named according to its appearance, with longitudinal keyway in the shaft sleeve appearance, rotating parts on the shaft also have corresponding keyway, can be maintained with axis synchronous rotating.

Gear spline shaft with high quality alloy steel intermediate frequency quenching HRC58, spline outer tube using high quality low carbon steel carburizing hard HRC58, therefore has a higher life and strength. Rolling spline pair can be transferred to the direction of clearance control to zero clearance, can be high-speed operation, high speed rotation, compact structure, assembly is simple (even if the gear spline shaft is drawn, the ball will not fall off).
