This is perhaps the most important comparison. DIN 5480 defines involute splines, which use a curved tooth profile, whereas DIN 5463 is for straight-sided splines. Involute splines offer advantages like higher load-carrying capacity, better self-centering properties, and greater strength. As a result, DIN 5480 has become the modern standard for new designs, with DIN 5463 now being considered a legacy standard .
The purpose of DIN 5463 is to ensure that keys and keyways are designed and manufactured to a standard that ensures:
___ ___ <-- Major Diameter (D) / \_/ \ | | | <-- Flank / Tooth Width (B) \___/ \___/ <-- Minor Diameter (d) Expressed as the minor diameter major diameter (e.g., Minor Diameter (
The standard specifies the geometry for splined shafts and bushes used in power transmission to ensure parts from different manufacturers are interchangeable. Features straight, parallel flanks. din 5463 pdf
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.
She specified internal centering (bore centering), as outlined in the DIN 5463 guidelines . 2. The Material Challenge
When consulting a , designers will find detailed tables covering several parameters. The standard generally categorizes profiles based on the number of splines and their dimensions. 1. Spline Profiles and Dimensions This is perhaps the most important comparison

Engineers and technicians often search for the to access precise dimensional charts required for machining and assembly. 1. What is DIN 5463?
The most authoritative and legally valid document for new projects is DIN ISO 14:1986-12 . This is the direct superseding standard and contains the same technical specifications as the former DIN 5463. You can purchase the official PDF from national standards organizations like DIN Media. As a result, DIN 5480 has become the
Because straight-sided splines distribute rotational force evenly across multiple parallel faces, they are vastly superior to single-keyway systems. DIN 5463 profiles are commonly found in:
