: Typically 6 to 10 keys, depending on the nominal size.
Many mechanical engineering suppliers (e.g., OmniGear) provide data sheets summarizing the DIN 5462 standard dimensions. Important Notes on the Standard din 5462 spline standard pdf exclusive
The spline standard is a testament to the enduring power of good engineering. Though officially withdrawn, its practical legacy is immense. The standard standardized the design of straight-sided splines for light series applications, enabling the mass production of reliable, interchangeable components that power everything from agricultural PTOs to commercial truck hydraulic systems. Its straightforward geometry continues to be a relevant and effective solution for these applications, albeit now under the ISO 14 umbrella. : Typically 6 to 10 keys, depending on the nominal size
Straight-sided splines can be accurately milled, broached, or slot-cut using standard manufacturing tooling. Common Industrial Applications Though officially withdrawn, its practical legacy is immense
Eliminates the need for intermediate drive shafts, universal joints, or coupling sleeves. The pump shaft slides directly into the PTO internal gear.
DIN 5462 represents a critical chapter in the history of mechanical power transmission. Its involute geometry provided—and continues to provide—a robust solution for high-torque, sliding connections.
