– This standard covers involute splines, which are a different geometry. Straight‑sided splines (DIN 5464) have a 0° pressure angle, whereas involute splines use a pressure angle (usually 30°). The choice between the two depends on the application: straight‑sided splines are especially suitable for thin‑walled hubs because the 0° flank angle creates no radial forces that would expand the hub.

The standard is favored in specific heavy-duty sectors because of its inherent design advantages:

This design prevents the hub from expanding under radial forces, making it exceptionally stable for high-torque applications. Centering Options:

It ensures proper alignment and centering of the shaft and hub. 3. Verification and Inspection

For engineers, designers, and manufacturers, accessing the is crucial for ensuring the structural integrity and interchangeability of shaft-hub connections. What is the DIN 5464 Standard? The DIN 5464 standard covers straight-sided splines with a 0∘0 raised to the composed with power

Understanding the why helps justify purchasing the PDF. You will find DIN 5464 fine-pitch flange nuts in:

No. DIN 5464 deals with straight‑sided splines (shaft‑hub connections). The standard that is often confused with it is DIN 564 , which covers hexagon head set screws with half dog point. There is also a standard DIN 546 for retaining rings, which is unrelated.

The current version of this standard is . It provides the exact geometry, dimensions, and tolerances required to manufacture these components. Why Use the Heavy Series?

) acts as the centering surface, it is frequently ground after heat treatment to achieve the final required tolerance zone (such as h6 or g6). 2. Hub Manufacturing
