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 Though officially withdrawn, its practical legacy is immense.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.
Understanding this German engineering standard ensures component compatibility, prevents mechanical failure, and optimizes torque transfer. What is the DIN 5462 Spline Standard?

The shaft and mating hub should share similar heat-treatment profiles (typically case-hardened to 58-62 HRC) to prevent one component from prematurely wearing out the other.
: While the 8-tooth version is standard for hydraulic pumps, the series includes sizes such as 6 x 23 x 26 and 6 x 28 x 32.

The DIN 5462 standard specifies the dimensions, tolerances, and design criteria for straight-sided (parallel) splines. Unlike involute splines—which feature curved tooth profiles—straight-sided splines utilize flat, parallel flanks.
specifically governs Involute Spline Profiles based on reference diameters.
The is a foundational technical specification in mechanical engineering, particularly within the automotive, mobile hydraulics, and agricultural machinery sectors. As part of the German Institute for Standardization (DIN) series, this standard defines the geometric dimensions and tolerances for straight-flanked spline shafts and hub connections (often referred to as the light series, Keilwellen-Verbindungen mit geraden Flanken ). Its straightforward geometry continues to be a relevant
The DIN 5462 standard was first published in 1966 by the Deutsches Institut für Normung (DIN), the German national standards organization. The standard was developed to provide a unified specification for splines used in various industries, including automotive, aerospace, and mechanical engineering. Over the years, the standard has undergone several revisions, with the most recent update being published in 2018.
The flat flanks provide excellent centering stability, which prevents high-pressure hydraulic fluid seals from distorting due to shaft runout.
