The DIN 5482 standard is a widely recognized German industrial specification for involute splines with a 30° pressure angle. While largely superseded by the newer DIN 5480 standard, it remains a critical reference for maintaining and repairing older machinery, particularly in European automotive and heavy industrial applications. Technical Specifications Profile Type: Involute (curved) teeth.
Pressure Angle: Always 30°, which provides a balanced distribution of radial and tangential forces.
Tooth Centering: Typically flank-centered, meaning the shafts and hubs align via the sides of the teeth rather than the diameters.
Dimensions: Sizes are usually designated by their nominal diameter (e.g., ) and the number of teeth ( Comparison: DIN 5482 vs. DIN 5480
Understanding the difference is vital for sourcing parts or creating CAD models.
DIN 5482 (Withdrawn): Uses a specific table of fixed dimensions for each size. It is less flexible but simpler to specify for legacy parts. DIN 5480 (Current): Uses a module-based system (e.g.,
), allowing for a much wider range of diameter and tooth combinations.
Compatibility: These standards are not interchangeable. A DIN 5482 shaft will not fit a DIN 5480 hub. Practical Applications
Hydraulic Pumps: Commonly used in gear pumps from manufacturers like Casappa.
Automotive: Found in older European steering columns and drivetrain components.
Gearboxes: Used in industrial transmissions that pre-date the mid-1980s. 🛠️ Design & Calculation Tools
Because the standard is withdrawn, finding official printed copies is difficult. Most engineers use software to generate profiles:
HEXAGON WN10: A dedicated tool for calculating dimensions, tolerances, and strength specifically for DIN 5482.
CAD Integration: Tools like SolidWorks can be used to manually model these profiles if you have the tooth data from the standard tables.
Reference Tables: Technical gear info and dimension charts are often hosted by specialized manufacturers like Omni Gear.
💡 Key Tip: When identifying an unknown spline, count the teeth and measure the outside diameter of the shaft. If it doesn't match modern module-based sizes, it is likely a legacy DIN 5482 profile.

To develop a feature based on the DIN 5482 spline standard, you must integrate specific geometric parameters that define these involute splines. While DIN 5482 is officially withdrawn and largely replaced by DIN 5480, it remains a critical legacy standard in automotive and industrial machinery for transmitting high torque loads. Key Specifications for Feature Development
When building a CAD tool, calculation script, or manufacturing feature, your "feature" should include the following parameters defined by the standard:
Involute Tooth Profile: Unlike straight splines, DIN 5482 uses an involute curve, which provides self-centering and higher load capacity. Module ( ): Determines the size of the teeth. Number of Teeth ( ): The total count of splines on the circumference. Pressure Angle ( ): Typically 30∘30 raised to the composed with power for these involute profiles. Reference Diameter ( ): Calculated as .
Tolerances: The standard defines specific classes (e.g., loose vs. tight) that dictate fitment and manufacturing cost. Implementation Workflow
Input Identification: Allow users to select the nominal size (e.g., ) from a standard DIN 5482 table. din 5482 spline standard pdf
Geometric Calculation: Use the standard's formulas to derive the tip diameter, root diameter, and tooth thickness.
Digital Integration: Utilize CAD simulation tools to generate the 3D tooth profile.
Validation: Ensure the design allows for "interchangeability," a primary benefit of adhering to the DIN 5482 criteria. Resources for Reference

The DIN 5482 standard is a German industrial specification for involute splines used to transmit torque between shafts and hubs. While officially withdrawn and replaced by DIN 5480 for new designs, it remains widely used for replacement parts and within the hydraulics and fluid flow industries. Key Technical Specifications
DIN 5482 defines the geometry and tolerances for splines with a 30° pressure angle.
Module System: Unlike modern standards that use a fixed module, DIN 5482 uses specific module groups (e.g., 1.6, 1.9, or 2.1) where the module and pitch are often unique to a specific diameter.
Dimensions: It specifies parameters such as the number of teeth ( ), major diameter ( ), and minor diameter (

This article provides an in-depth look at the DIN 5482 spline standard, its technical specifications, and how to source the necessary PDF documentation for your projects. 🛠️ What is the DIN 5482 Standard?
DIN 5482 is a German standard for involute splines with 30-degree pressure angles. Unlike newer standards that focus on module-based sizing, DIN 5482 is based on the pitch diameter and the number of teeth, often resulting in specific "profile offset" (correction) values to maintain fit. Key Characteristics: Pressure Angle: 30° Profile: Involute (curved tooth flanks) Fit Type: Primarily flank-centered
Application: Heavy-duty power transmission, pumps, and gearboxes 📋 DIN 5482 vs. DIN 5480: The Major Differences
The most common question engineers ask is: “Can I swap DIN 5482 for DIN 5480?” The short answer is no. While they look similar, their geometry is fundamentally different. DIN 5482 (Old) DIN 5480 (New) Status Withdrawn (but still widely used) Current / Active Sizing Based on fixed diameters Based on Modules (m) Pressure Angle Interchangeability Not compatible Not compatible 📐 Technical Specifications & Table Data
When searching for a DIN 5482 spline standard PDF, you are likely looking for the dimension tables. These tables define the "N" (Internal/Hub) and "A" (External/Shaft) measurements. Common Size Designations:
A DIN 5482 spline is typically called out by its nominal size. For example: DIN 5482 N20 x 17: Internal spline, ~20mm major diameter. DIN 5482 A30 x 27: External spline, ~30mm major diameter. Standard Dimensions (Example Snippet): Nominal Size Number of Teeth (z) Module (m) Pitch Circle 📥 Accessing the DIN 5482 PDF
Because DIN 5482 is technically a "withdrawn" standard, finding official copies can be tricky. However, it is still available through several professional channels:
Beuth Verlag: The official distributor of German (DIN) standards. Even withdrawn standards are usually available for purchase in digital PDF format.
Standards Aggregators: Websites like IHS Markit or ANSI often host legacy DIN documents.
Machinery Handbooks: Many European engineering handbooks (like the Dubbel Handbook) contain the core tables of DIN 5482. ⚙️ Manufacturing DIN 5482 Splines
Manufacturing these splines requires specific tooling. Because the standard uses unique pitch diameters, a standard DIN 5480 hob will not work. Hobbing: Requires a dedicated DIN 5482 hob cutter.
EDM: Wire Electrical Discharge Machining is often used for small batches or hardened parts using the CAD profiles derived from the standard. Broaching: Common for high-volume internal splines. ⚠️ Important Considerations for Engineers
If you are designing a new system, it is highly recommended to use DIN 5480 instead of DIN 5482. The newer standard offers: Better availability of off-the-shelf tooling. More comprehensive calculations for tolerances and fits. Easier integration with modern CAD/CAM software.
However, for repairs or replacement parts on existing European machinery, adhering to the original DIN 5482 specs is mandatory to ensure a proper fit.

Once you have the PDF, here is a step-by-step workflow to implement it:
Unlike DIN 5480 which uses a reference diameter, DIN 5482 uses the module (the ratio of pitch diameter to number of teeth). Common modules include 0.5, 0.6, 0.8, 1.0, 1.25, and 1.5. The DIN 5482 standard is a widely recognized
