Din 5464 Standard Pdf Jun 2026

The standard specifies the requirements for straight-sided splines in the heavy series , designed for both fixed and moving shaft-hub connections . This standard is critical in mechanical engineering for transmitting high torque through thin-walled hubs, as its 0∘0 raised to the composed with power pressure angle prevents hub expansion from radial forces. Key Specifications of DIN 5464

Details the nominal dimension blueprints for shafts and hubs.

The standard typically covers diameters from up to M36 x 3 (fine pitch variations). Note that the pitch differs per diameter (e.g., M10 x 1.25, M12 x 1.5, M16 x 1.5). din 5464 standard pdf

– This is the international standard for straight‑sided splines with internal centering. The heavy series defined in DIN 5464 has more splines than DIN ISO 14, which increases the load capacity, but also requires more precise manufacturing.

The current active version of this technical standard is . It replaced older editions such as the historical 1965 version.

Unlike newer involute spline designs, straight-sided (or parallel-sided) splines remain a critical component in manufacturing due to their high load capacity and straightforward machining requirements. What is DIN 5464? The heavy series defined in DIN 5464 has

Defines the physical profile of the splines for both the shaft and the hub.
