DIN 5480 is the German standard for , widely used in mechanical engineering for high torque transmission and precise alignment. Unlike other standards that rely on the major or minor diameter, DIN 5480 uses a reference diameter ( dBd sub cap B

Designated with lowercase letters (e.g., 7h , 8g , 8f ). An f or g tolerance produces a loose, free-sliding fit.
: Designates the part type. W stands for Welle (Shaft/External spline). N stands for Nabe (Hub/Internal spline).
The cornerstone of DIN 5480 is the . This diameter remains constant for all splines with the same nominal size, regardless of the module chosen. Its primary purpose is to allow the shaft and hub to be fitted optimally to standard bearing seat diameters. This feature drastically reduces the number of different tools (like hobs and broaches) needed for manufacturing, leading to significant cost savings and increased design flexibility.
Involute splines are critical mechanical components used to transmit high torque between shafts and gears. Among the various international standards, the German standard is widely recognized as the industry benchmark for metric involute splines with a 30° pressure angle. Choose an appropriate Module ( Assume you have
The reference diameter allows for standardization with ball and roller bearings.
Here are the key dimensions for each type:
DIN 5480 is a German standard defining involute spline connections with straight-sided (parallel) sides on the tooth flanks used for transmitting torque between shafts and hubs. It standardizes geometry, tolerances, fits, and inspection dimensions to ensure interchangeability and predictable load capacity.
