Spline shaft
 
@1. Durability
Thanks to GROB spline method, our hardness of the surface is getting harder ( more than Hv250 ) and its roughness is less than 0.7ƒÊ‚qmax, very smooth condition. The sliding movement of nut is excellent.
@‚QDMechanical Property

Fiber flow inside the shaft remains along the teeth profile . The micro structure of teeth bottom becomes dense. This feature gives the spline the strong fatigue strength.

The fiber, remained un-cutted, makes the mechanical property stronger.
