SAE specifies mounting requirements in addition to dimensions and gauges. SAE standard splines are measured in standard rather than metric. SAE Spline: Similar to ISO standards, the Society of Automotive Engineers (SAE) splines meet standards for safety and efficiency.Splines manufactured to ISO-14 standards meet specific dimensional, control, and gauge standards for light, medium, and heavy use. ISO-14 Straight Sided Splines: Based on International Organization for Standards (ISO) guidelines, these splines are categorized using metric measurements in millimeters.Involute Spline: Involute splines feature gear like teeth that enhance surface contact and distribute force in a way that reduces stress on the splines while transmitting extremely high torque.Grob Standard Spline Shaft: Grob standard spline shafts are engineered to ensure maximum contact and torque using an even number of teeth and parallel over 2 or more teeth to be self centering.Spline shafts can be divided into five categories: Spline shaft manufacturers create shafts in a range of diameters, tooth angles, and groove depths to facilitate numerous operations.
