Don't rely on guesswork for your spline geometry. Ensure your tolerances are correct and your stress calculations are based on the official data.
For more detailed information, you can download the DIN 5462 standard PDF from the DIN website or other authorized sources. The PDF provides a comprehensive overview of the standard, including dimensions, materials, and tolerances.

Engineers often confuse DIN 5462 with the broader international standard, (or its regional equivalent, DIN 5463). While both cover straight-sided splines, they serve different purposes: ISO 14 / DIN 5463 Primary Use Case Hydraulic pumps, PTO truck gearboxes. General mechanical engineering. Tooth Count Fixed standard sizes (predominantly 8 teeth). Light and medium series variants (6 to 20+ teeth). Centering Type Strictly minor diameter centering. Can support both minor diameter and flank centering.

All copies are considered historical and are typically locked behind the paywalls of official standards bodies. However, obtaining a digital copy is still possible through legitimate channels.
Used as the male drive shaft for heavy-duty dump truck pumps, axial piston pumps, and bent-axis motors (e.g., Rexroth, Parker, or Sunfab styles). Don't rely on guesswork for your spline geometry

The Definitive Guide to the DIN 5462 Spline Standard: Engineering, Applications, and Specifications
The DIN 5462 standard specifies the dimensions, tolerances, and requirements for splines with a straight-sided or involute tooth profile. The standard covers splines with a module (m) range of 0.5 to 10 mm and a number of teeth (z) ranging from 6 to 100. The key features of DIN 5462 splines include: The PDF provides a comprehensive overview of the
in the "light series," commonly used for high-torque connections in truck Power Take-Offs (PTOs) and hydraulic pumps. It has largely been superseded by the
specifies the dimensions for splines with straight flanks, where the torque is transmitted through the sides of the teeth, not the root or outer diameter. It falls under the "Light Series" of spline standards, meaning it is designed for applications where space is limited and load requirements are moderate to high, but not extreme (compared to DIN 5480 involute splines). Key Features of DIN 5462 Splines: Straight-flanked profiles: Teeth have flat, parallel sides.
On dump trucks, crane trucks, and refuse vehicles, the gearbox features a PTO output. This output almost exclusively utilizes a DIN 5462 internal 8-tooth profile to drive the auxiliary hydraulic system. 2. Hydraulic Piston and Gear Pumps
