The standard specifies the dimensions and tolerances for straight-sided (parallel) metric splines in the "light series". While the original DIN 5462 standard is technically superseded by DIN ISO 14 , it remains the primary industry reference for hydraulic pumps and power take-off (PTO) units, particularly the common 8 x 32 x 36 profile. Core Dimensional Data
Below are the nominal dimensions for the DIN 5462 Light Series. All measurements are in millimeters (mm). Nominal Size (N x d x D) Number of Keys (N) Inside/Minor Dia (d) Outside/Major Dia (D) Key Width (B) 6 x 23 x 26 6 x 26 x 30 6 x 28 x 32 8 x 32 x 36 8 x 36 x 40 8 x 42 x 46 8 x 46 x 50 🛠️ Key Design Details Centering: The standard typically uses internal centering (on the minor diameter Tolerances: Common fits include for the bore and for the shaft, depending on the application.

One element often missing from free online calculators is the centering instruction . DIN 5462 requires manufacturers to explicitly state whether centering is on the major diameter (D), minor diameter (d), or flanks (b). The PDF standard contains the exact flowcharts for these designations. The standard specifies the dimensions and tolerances for
