Many technical university libraries maintain access to historical standards databases:
DIN 5482 is a German standard titled "Involute splines for cylindrical shafts and holes with side fit – Dimensions and stress calculation." Unlike the more globally common DIN 5480 or ISO 4156, DIN 5482 focuses on light to medium-duty involute splines with a root fit (as opposed to side fit only).
No. If you are designing a new product, use ISO 4156. It is supported by every modern tool library, broach manufacturer, and inspection probe.
But. If you are repairing, reverse-engineering, or interfacing with legacy German equipment, you have no choice.
The din 5482 spline standard file type pdf77 is more than a file. It is a digital fossil. It represents a decade of German precision engineering trapped in a format that is legally orphaned, technically obsolete, but mechanically vital.
Pro tip for the working engineer: Do not just save the PDF. Create a spreadsheet calculator. Input the module and tooth count, and have it output the over-pin measurements (using 20° pressure angle pins). That spreadsheet will be worth more to your shop floor than the original standard ever was.
Because in the end, the standard isn't the paper. It isn't the PDF. It's the fit between the shaft and the hub—that silent, metallic handshake that has been turning smoothly since 1977.

Understanding the DIN 5482 Spline Standard standard is a legacy German specification for involute splines, primarily used for shaft-hub connections where torque transmission and centering are required. While technically and officially replaced by the more modern DIN 5480 standard
, it remains widely relevant in modern engineering, particularly for replacement parts and specific sectors like the hydraulics industry. hexagon.de Key Characteristics of DIN 5482
Unlike many modern standards that use a 30° pressure angle, DIN 5482 is distinctive for its specific geometry and historical application: Pressure Angle: Typically utilizes a 30° pressure angle Module System:
Features unique module sizes (e.g., 1.9 module) that are not common in other standards. Interchangeability: not interchangeable
with DIN 5480. Tools designed for DIN 5480 generally cannot be used for DIN 5482 because the pitches and whole depths vary significantly. Tooling Constraints:
Generating tools for DIN 5482 often do not cover the full range of teeth within a single pitch, sometimes requiring multiple cutters for different depths. Status and Replacement
The standard was officially withdrawn in the late 20th century. Official sources like the DIN Media portal Accuris Standards Store list it as "Withdrawn," advising engineers to use
for all new designs. However, due to the vast amount of existing machinery still in operation, many software suites like HEXAGON WN10
still provide full calculation and database support for DIN 5482 dimensions. hexagon.de Digital Access and Files (PDF)
Detailed specifications, including tooth profiles and measurement tables (using pins or balls), are typically found in the following parts: DIN 5482-1: Focuses on dimensions for internal and external profiles. DIN 5482-3:

The DIN 5482 standard is a German technical specification for involute splines—mechanical components that transmit torque between shafts and mating parts like gears or pulleys. While it was officially withdrawn and replaced by the more modern DIN 5480 standard, DIN 5482 remains critical for maintaining and repairing older machinery, particularly in the hydraulics and fluid flow industries. Overview of DIN 5482 Standard
DIN 5482 specifically covers fine-module involute splines with a pressure angle of 30°. Unlike its successor, DIN 5480, it uses a varied set of modules—some of which are uncommon today, such as the 1.9 module. Status: Obsolete/Withdrawn. Replacement: DIN 5480 for all new designs.
Core Geometry: Based on the reference diameter, module, and number of teeth.
Applications: Frequently found in legacy tractors, hydraulic motors, and specialized agricultural machinery. Technical Specifications
The standard is divided into multiple sheets that define dimensions for internal and external splines: Specification Details Pressure Angle Module Range din 5482 spline standard file type pdf77
Includes uncommon sizes like 1.9, 2.1, and standard modules like 1.6 or 2.0 Fit Types
Flank-centered with options for sliding, interference, or force fits Tooth Profiles
Internal profiles often require tip chamfering to ensure smooth assembly Comparison: DIN 5482 vs. DIN 5480
Engineers often need to distinguish between these two because their tooling is not interchangeable.
Tooling Flexibility: DIN 5480 tools can cut all numbers of teeth within a specific pitch. In contrast, DIN 5482 may require several different cutters for a single pitch due to varying whole depths.
Design Philosophy: DIN 5482 dimensions were specifically chosen so that major and minor diameters align well with standard bearing sizes available at the time of its creation.
Modern Usage: DIN 5480 is the global standard for new metric involute splines, while DIN 5482 is strictly for spare parts and "re-engineering". Software and PDF Resources

DIN 5482 is an older German industrial standard that specifies the dimensions and tolerances for involute splines with a 30° pressure angle. While it has been technically withdrawn and replaced by the more modern DIN 5480 for new designs, it remains widely used for spare parts and within specific sectors like the fluid power industry. Key Specifications
Profile Type: Involute tooth profile, which ensures smooth engagement and uniform load distribution. Pressure Angle: Fixed at 30°.
Usage: Primarily for connecting rotating components like shafts and gears to transmit torque.
Replacement: For any new mechanical design, it is recommended to use DIN 5480 or international standards like ISO 4156. Core Parameters The standard outlines specific measurements for: Module (
): The basic size parameter (e.g., common modules like 1.9 or 2.0). Number of Teeth ( ): Influences torque capacity and engagement smoothness.
Diameters: Major, minor, and pitch diameters for both internal and external splines.
Tolerances: Defines fit classes (clearance or interference) to manage backlash and ensure proper assembly. Software and PDF Resources Din 5482 | PDF - Scribd
The DIN 5482 standard remains a critical historical reference for involute splines, though it has been officially withdrawn and superseded by the more modern DIN 5480 standard. Despite its obsolete status, it is still frequently encountered in the maintenance and repair of legacy equipment, particularly within the hydraulics and fluid power industries. Historical Context and Status
Originally established in 1950 and updated in 1973, DIN 5482 was the primary German standard for involute splines with a 30° pressure angle.
Withdrawal: The standard was officially withdrawn in the late 20th century.
Current Application: According to DIN Media, the standard should now only be used for replacement parts in existing machinery. For any new mechanical designs, the DIN 5480 series is the mandatory replacement. Technical Characteristics
DIN 5482 differs from its successor in how it defines the relationship between the number of teeth and the module. WN10 - Involute Splines according to DIN 5482 Have you found a clean copy of the DIN 5482 1977 tables

Limitations and Future Research
This investigation has provided an overview of the DIN 5482 spline standard PDF77. Future research could focus on:
| Feature | DIN 5482 | ISO 4156 / DIN 5480 | |---------|----------|----------------------| | Pressure angle | 30° only | 30°, 37.5°, 45° | | Root shape | Flat root | Full fillet | | Module range | 0.5 – 2.5 mm (common) | 0.5 – 10 mm (or more) | | Fit type | Side fit only | Side fit or major diameter fit | | Standard status | Superseded nationally | Active international |
Modern designs favor ISO 4156 because it offers higher torque density (via 45° angle) and better fatigue life (full root fillet). However, replacement parts and repair of older German machinery require adherence to DIN 5482.
