Depending on the application (e.g., agricultural machinery), they may be hardened and tempered.
Published in the mid-to-late 20th century and reaffirmed in various editions (most notably the 1976-10 version), this standard specifies the dimensional characteristics of straight-sided spline profiles. Unlike involute splines (DIN 5480 or ISO 4156), straight-sided splines have parallel flanks, making them simpler to manufacture but less optimal for high-stress applications.

DIN 5463 is a German standard (Deutsches Institut für Normung) that specifies the requirements for involute splines and their corresponding mating parts. The standard covers the dimensions, tolerances, and testing of splines used in various industries, including automotive, aerospace, and mechanical engineering.
Typically broached or slotted to H7 on the minor diameter. Flank Fit (Width din 5463 pdf
Involute splines are widely used in various industries, including:
The Complete Guide to DIN 5463 Splines: Specifications, Dimensions, and PDF Resources
A spline designation like indicates: 8: Number of teeth (n) 46: Inside Diameter (d₁ in mm) 54: Outside Diameter (d₂ in mm) Key Dimensions to Consider (Medium Series):
DIN 5463 is a fundamental standard for designing robust metric parallel spline connections. By adhering to the dimensions and tolerances specified in a , engineers can ensure that their shaft and hub connections are durable, properly aligned, and interchangeable with standard components. Depending on the application (e
Despite being replaced by ISO 14 (Straight-sided splines for cylindrical shafts with internal centering), the designation "DIN 5463" remains incredibly popular in European workshops, legacy blueprints, and aftermarket parts catalogs. Manufacturers frequently cross-reference DIN 5463 with ISO 14 because their dimensions and fitment characteristics are nearly identical. How to Find and Download a DIN 5463 PDF
