To verify the physical spline during manufacturing, calculators compute the for shafts, and Measurement Between Pins ( Mkcap M sub k ) for hubs.

A DIN 5482 spline connection is defined by five key parameters:

While a proper calculator is the most flexible tool, reference data for common DIN 5482 sizes is sometimes available from suppliers. The table below illustrates typical parameters for standard part numbers: din 5482 spline dimensions calculator

Typically designed as a side-bearing fit, allowing slight radial clearance between the major and minor diameters.

A tighter tolerance class reduces the backlash (slop) in the system. However, it also demands highly precise manufacturing processes, such as broaching or wire EDM shaping, which increases production costs.

Internal and external involute splines are critical for transmitting torque in mechanical drive systems. While the standard was officially withdrawn and replaced by the newer DIN 5480 standard, it remains widely used in legacy machinery, hydraulic pumps, agricultural equipment, and automotive gearboxes worldwide.
