Power Take-Off (PTO) gearboxes mounted to truck transmissions frequently use a DIN 5462 4-bolt, 4-spline output interface.
While involute splines (such as those governed by DIN 5480 or DIN 5482) dominate high-speed automotive drivetrains, the straight-sided DIN 5462 profile remains a industry staple for heavy-duty hydraulics due to several specific advantages:
The most common iteration of this standard found in industrial catalogs is the profile. The alphanumeric designation provides all the fundamental geometric data required for machining or inspection. Dimensional Breakdown Nominal Measurement Description Number of Teeth ( ) Total parallel slots/teeth around the circumference. Minor Diameter ( ) The inner diameter of the spline shaft (root circle). Major Diameter ( ) The outer diameter of the spline shaft (tip circle). Spline Width ( ) The lateral thickness of an individual straight tooth.

The Definitive Guide to the DIN 5462 Spline Standard: Specifications, Applications, and Key Differences
The most dominant variant under this standard is the profile. The numbers represent a specific geometric blueprint: 8 : The total number of teeth (or slots). 32 mm : The minor diameter ( Spline Width ( ) The lateral thickness of
Unfortunately, I couldn't find a publicly available PDF of the DIN 5462 standard. As a copyrighted document, it's typically only accessible through:
Spline shafts and hubs are critical components in mechanical power transmission, ensuring the synchronized transfer of torque between rotating elements. In European automotive, agricultural, and hydraulic machinery, the standard defines a widely used straight-sided spline profile. the minor diameter
The standard defines the profile based on the number of keys (splines), the minor diameter, and the major diameter. : Parallel-sided (straight flanks). Common Dimensions (8 x 32 x 36) : Number of Keys : 8. Minor (Inside) Diameter : Major (Outside) Diameter :
