Pdf: Din 5480

A DIN 5480 designation is a compact code that fully describes a spline connection. The format is:

If you are replacing a component on a machine built in Europe, you will almost certainly require the metric DIN 5480 data sheets rather than the imperial ANSI equivalent.

Choose flank-centered for better load distribution, or diameter-centered for better concentricity.

The price for a DIN standard PDF varies by vendor and usually ranges from around €70 to €150 per part. Here are some official distributors:

: You calculate specific load data and verify actual flank pressure for a more precise engineering fit. Where to Find the Official PDF Din 5480 Pdf

Under load, the forces naturally center the hub onto the shaft, minimizing runout.

: Under torque, the forces center the shaft inside the hub automatically.

When you see a drawing callout like:

DIN 5480 is a German Institute for Standardization (Deutsches Institut für Normung) standard that defines based on reference diameters. Unlike older systems (like DIN 5462 or DIN 5463) which used a straight-sided tooth profile, DIN 5480 uses an involute profile.

based on reference diameters. It is widely used in mechanical engineering to connect shafts and hubs for transmitting torque while allowing for easy assembly with standard components like bearings. Core Principles of DIN 5480 Reference Diameter System

: Side-fit (flank centering) is the standard method, though diameter centering is permitted in exceptional cases. Standard Structure & Parts

Represented by lowercase letters (e.g., 9g, 8f). Letters further down the alphabet create larger fundamental deviations, resulting in looser or tighter fits. A DIN 5480 designation is a compact code

❌ Assuming DIN 5480 is identical to ISO 4156. They are not interchangeable . ISO 4156 uses basic pitch diameter; DIN 5480 uses reference diameter. Gauges differ.

is the German industrial standard for involute splines based on reference diameters. Unlike many other standards, it uses a module-based system to define the teeth, which allows for standardized calculations of torque transmission and flank pressure. The price for a DIN standard PDF varies
