DIN 5480 is the German standard for involute splines with a 30° pressure angle, widely used in the automotive, hydraulic, and aerospace industries. Unlike many other standards, DIN 5480 is based on that are independent of the module, allowing for easy integration with standard bearing sizes. Key Components of DIN 5480 is the tolerance class (5–12); f is the
