is a German technical standard that defines the dimensions and tolerances for metric parallel spline shaft connections with straight flanks (medium series). It has largely been superseded by the international standard ISO 14 . Core Technical Specifications
The PDF version of DIN 5463 typically includes:
The standard covers spline shaft profiles (designated A or B) and corresponding splined bores. Common profile sizes include:
The official publisher of German national standards. This is the safest source for the fully revised, legally compliant version of the text.
Alignment between the shaft and the hub is primarily maintained by the minor diameter (
The standard specifies the dimensions, tolerances, and design requirements for metric parallel spline shaft connections . Originally published in 1955, it has largely been superseded by the international standard ISO 14 , though it remains a common reference in industrial catalogs and technical drawings for "medium series" straight-sided splines. Overview of DIN 5463
This standard specifies dimensions for splined shafts and hubs that transmit high torque in mechanical engineering.
Frequently manufactured from Steel (e.g., C45, ST 52.3, EN8) or Bronze (e.g., RG 7) for bushings. Dimensions and Designation
DIN 5463 is a German technical standard established by the Deutsches Institut für Normung (German Institute for Standardization). It specifies the dimensions, profiles, and tolerances for with internal centering.
: While many engineers still search for a DIN 5463 PDF , the modern official document is DIN ISO 14 , which provides identical geometric data for these medium series profiles. Standard Dimensions Table (Medium Series)
Power Take-Off (PTO) shafts, tractor attachments, and drive systems often utilize parallel splines due to their resistance to dirt and ease of sliding engagement.
