Before diving into dimensions, it is critical to understand what DIN 5480 actually specifies. Issued by the Deutsches Institut für Normung (DIN), this standard covers Involute splines based on reference diameters . Unlike older standards (like DIN 5463 or DIN 5464) which used straight-sided splines, DIN 5480 uses an involute tooth profile.

Remember that "Effective" size includes errors in pitch and profile, whereas "Actual" is just the tooth thickness. If you'd like to calculate specific values , tell me: The Reference Diameter (e.g., 50mm) The Module (e.g., 2) Whether it is a Shaft or a Hub

A typical DIN 5480 designation, such as DIN 5480 – W 120 x 3 x 38 x 8f , provides a complete dimensional profile: : Denotes a Shaft ( Welle ) or Hub ( Nabe ). 120 : The reference diameter in millimeters. 3 : The module ( ), indicating the tooth size. 38 : The number of teeth (

In the world of precision mechanical engineering, the interface between a shaft and a hub is critical. When it comes to transmitting high torque while allowing for sliding or fixed connections, involute splines are the gold standard. Among the most widely adopted standards globally is .

The is a widely recognized German engineering specification for involute splines based on reference diameters. Unlike other standards that center on major or minor diameters, DIN 5480 is uniquely structured to allow splined components, such as ball bearings, to be easily slip-fitted onto shafts.
