Unlike involute splines (which feature angled tooth profiles), straight-sided profiles feature a . This distinct mechanical structure completely prevents the generation of radial forces during torque transmission. Because there are no radial forces attempting to push the shaft and hub apart, the hub does not experience radial expansion. This design allows engineers to transmit exceptionally high torques while utilizing remarkably low hub wall thicknesses. Heavy Series vs. Standard Light Series din 5464 standard pdf
