If your machine was built before 1990, you likely need DIN 5482. If newer, use DIN 5480.
indicates a hub (internal spline), while A indicates a shaft (external spline). 22 represents the nominal major diameter. 19 represents the nominal minor diameter. DIN 5482 vs. DIN 5480: The Evolution

It utilizes a fixed 30-degree pressure angle.
Some engineers share personal scans for reference.
Many tooling suppliers still reference DIN 5482 when cataloging standard off-the-shelf broaches. If a design engineer specifies a hub according to DIN 5480, they may inadvertently request a custom-made broach, increasing cost and lead time. Conversely, specifying a DIN 5482 spline allows the manufacturer to use a standard tool already in inventory. If your machine was built before 1990, you
Unlike modern standards that focus on standardized reference diameters, DIN 5482 is built around specific module groups and tooth counts tailored for existing tooling. Standardized at 30° across all profiles. Key Components:
Navigating technical archives for specific documentation, such as a , requires a firm understanding of the standard’s geometric principles, module system, and core differences from modern alternatives. What is the DIN 5482 Standard?
The DIN 5482 standard is a widely used and highly respected standard for splines in Europe. Its specifications ensure high precision, interchangeability, and a wide range of applications. If you're looking for a reliable and precise spline standard, DIN 5482 is definitely worth considering. 22 represents the nominal major diameter
