The DIN 5462 standard is a staple in fluid power and mobile hydraulic machinery. You will find it extensively utilized in:
: Profiles are commonly produced via hobbing ; however, internal centering may not be possible for all profiles when using this process.
The most dominant variant under this standard is the profile. The numbers represent a specific geometric blueprint: 8 : The total number of teeth (or slots). 32 mm : The minor diameter ( din 5462 spline standard pdf exclusive
Commonly machined to h7 , h8 , or js7 to ensure a controlled slide fit or light interference fit.

) grease during assembly, or ensure the spline is flooded with transmission/hydraulic oil.
The standard specifies nominal sizes based on: The numbers represent a specific geometric blueprint: 8
For the professional engineer, the cost of a mistake (scrapped parts, downtime) far exceeds the €90 price tag of the official document. However, for the home machinist or student, accessing the PDF via an or a Maschinenelemente textbook provides 99% of the data.
Parallel-sided splines offer uniform clearance along the flanks. This allows components—like a PTO sleeve or pump coupling—to slide axially under low-load conditions without binding. 3. Structural Rigidity Fewer teeth mean the core shaft diameter (
To help provide the specific engineering formulas or dimensional drawings you need, could you share a bit more about your project? If you'd like, let me know:
), measured at the tip of the external shaft or the root of the internal hub. : The nominal tooth width ( ) or slot width ( 2. Centering Method
