DIN 5482 predominantly utilizes flank centering (the teeth make contact on the sides/flanks). DIN 5480 also prioritizes flank centering but offers highly systematized fit classes for flexible clearance control.
DIN 5482 represents a manufacturing-centric approach to spline design, prioritizing the geometry of the cutting tool (the broach) over the geometry of the mating shaft. While DIN 5480 is the correct choice for new designs due to its global acceptance and shaft-based logic, DIN 5482 remains a

In mechanical power transmission, splined shafts and hubs are essential for transmitting torque while allowing relative axial movement. Among the many national and international spline standards, occupies a unique historical and technical position. Developed in Germany, this standard defines involute splines with a pressure angle of 30° , a low root stress concentration , and a modular tooth system tailored for automotive steering columns, pumps, and other compact drive systems. Although superseded in many applications by ISO 4156 and ANSI B92.1, DIN 5482 remains widely used in legacy designs and repair manuals. This essay explores the key characteristics, calculation methods, applications, and limitations of the DIN 5482 standard, demonstrating its enduring relevance in mechanical engineering.
Determine if you are cutting an internal (N) or external (A) profile.
: DIN 5482 dimensions were specifically chosen so that major and minor diameters align well with standard bearing sizes available at the time of its creation.
The answer was a low profile shift coefficient (typically x = 0.45 to x = 0.6 ). This creates a spline that is stronger in torsion than a straight-sided spline, but easier to broach than a full-depth involute. DIN 5482 predominantly utilizes flank centering (the teeth
Hydraulic pumps, heavy-duty gearboxes, and agricultural tractors manufactured between 1970 and 2000 rely entirely on DIN 5482 connections. Replacing a single worn shaft requires matching the legacy profile perfectly.
| Module | No. of Teeth | Outer Diameter Shaft (mm) | Root Diameter Shaft (mm) | Tolerance Class 1 (tight) | |--------|--------------|---------------------------|--------------------------|----------------------------| | 2 | 24 | 50.00 | 45.60 | 8f | | 2.5 | 20 | 55.00 | 49.50 | 9f | | 3 | 18 | 60.00 | 53.40 | 10f |
The primary source of confusion—and the reason DIN 5482 documents remain sought after—lies in the fundamental difference in how the "internal spline" is defined relative to the tooling used to create it.
