The DIN 5462 standard specifies the following key dimensions for splines:
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 :
Originally developed for applications requiring a robust, non-self-centering spline connection—such as agricultural machinery, heavy-duty gearboxes, and universal joint shafts—DIN 5462 has been largely superseded in modern German engineering by DIN 5480 (involute). However, it remains where compatibility with older ISO standards is required.
