standard, originally released in 1950, specifies the dimensions and gauging for involute spline joints 30 raised to the composed with power
pressure angle. Although it was withdrawn and replaced by the more modern
standard in the late 1980s, it remains a critical reference for maintaining and repairing older machinery, particularly in European automotive and industrial sectors. 1. Historical Context and Supersession
While DIN 5482 is still widely used in legacy systems, the newer DIN 5480 standard is now the preferred engineering choice. Uses a fixed tooth height and varying reference diameters.
Utilizes reference diameters independent of the module, allowing for better integration with standardized ball and roller bearings. 2. Technical Specifications
The DIN 5482 standard is characterized by the following design parameters: Pressure Angle: Standardized at 30 raised to the composed with power Tooth Profile:
Involute, providing high strength and ease of centering under load. Application: din 5482 spline standard pdf
Primarily used for shaft-to-hub connections to transmit high torque with minimal clearance. Dimensions:
Sizes are typically designated by the reference diameter and module (e.g., 3. Calculation and Design Tools
Because DIN 5482 is no longer an active standard, many engineers rely on specialized software for precise calculations: WN10 Software:
A commonly used tool for calculating dimensions and strength of splines according to the 1950 release of DIN 5482. CAD Export: Modern software can export true-scale tooth profiles as DXF or IGES files for integration into CAD systems. 4. Accessing the Standard
As an official standard, the full text and data tables are not legally available for free download as a public PDF. You can purchase the official German or English translations through the DIN Media portal
standard, which covers involute splines with a 30° pressure angle, was officially withdrawn in 1987 and replaced by
. Despite its obsolete status, it remains widely used today, particularly for replacement parts in the hydraulics and fluid flow industries because its dimensions were specifically designed to align with common bearing sizes. Key Specifications & Differences
While DIN 5482 is similar to the modern DIN 5480, it has unique characteristics that make them non-interchangeable: Module Range
: Primarily covers fine-module splines and uses some "uncommon" pitches, such as the 1.9 module. Pressure Angle : Standardized at 30°.
: Internal profiles typically require tip chamfering, which differs from modern standard tooling.
: Current engineering guidelines state DIN 5482 should only be used for repairs or replacement orders; all new designs should utilize Accessing the Standard (PDF & Data)

The DIN 5482 standard is a legacy German specification for involute splines with a 30∘30 raised to the composed with power
pressure angle, primarily used in mechanical engineering to connect shafts and hubs for power transmission. While officially withdrawn and replaced by newer standards like DIN 5480, it remains a critical reference for maintaining and repairing older machinery. 1. Purpose and Application
The primary goal of the DIN 5482 standard is to provide a uniform system for creating teeth on shafts and internal bores. These teeth interlock to transmit torque while allowing for axial movement if necessary.
Key Industries: It was widely adopted in automotive, heavy machinery, and hydraulic pump manufacturing.
Replacement Status: It has been superseded by DIN 5480, which offers a more comprehensive range of modules and diameters based on reference diameters rather than fixed pitch diameters. 2. Technical Characteristics
DIN 5482 is distinguished by several specific design parameters that engineers must account for when sourcing replacements or manufacturing new parts: Pressure Angle: It utilizes a 30∘30 raised to the composed with power
pressure angle, which provides a robust tooth profile capable of handling high loads.
Module-Based System: Dimensions are calculated based on the "Module" (the ratio of the pitch diameter to the number of teeth), a common metric in European gearing.
Fitment Type: The standard typically defines "side-fit" splines, where the load is carried on the flanks of the teeth rather than the major or minor diameters. 3. Sourcing and PDF Documentation
Finding the original DIN 5482 documentation in PDF format can be challenging because it is an "obsolete" standard. However, several resources remain available for technical data:
Official Standards: You can often find historical versions or replacement guidelines through the Beuth Publishing House, the official distributor of DIN standards.
Manufacturer Catalogs: Many hydraulic pump manufacturers, such as Bosch Rexroth, still include DIN 5482 tables in their technical catalogs to support legacy equipment. With the correct PDF and this guide, you
Data Sheets: Technical summaries and dimensions for specific DIN 5482 sizes (like the common 25x22 or 30x27) are often hosted on engineering portals to assist in part identification. 4. Why Use DIN 5482 Today?
Despite being officially withdrawn, the standard is far from "dead." Engineers frequently encounter it when:
Retrofitting: Replacing a failed hydraulic motor or pump on an older tractor or industrial machine.
Custom Fabrication: Creating adapters to bridge old DIN 5482 equipment with modern DIN 5480 or ANSI B92.1 components.
Global Supply Chains: Many regional manufacturers outside of Germany still produce "DIN 5482 compliant" shafts because the tooling is widely available and the standard is well-understood.
In summary, while DIN 5482 is no longer the "current" standard for new designs, its legacy in industrial hardware ensures that its technical specifications and PDF data sheets remain essential tools for the modern mechanical engineer.
DIN 5482 defines multiple fit classes, typically denoted by letter codes for centering:
Typical tolerance classes include close fits (e.g., H7/g6) for precise positioning and loose fits for ease of assembly.
You might wonder: if the standard is withdrawn, why do people still search for the DIN 5482 spline standard PDF? Here are the real-world reasons:
DIN 5482 is a German standard that specifications for involute spline connections. Unlike the simpler DIN 5480, DIN 5482 is specifically tailored for spline connections where the dimensional calculations are based on the reference diameter. It is widely cited in engineering contexts, particularly in the automotive and heavy machinery sectors within German-influenced markets. However, users searching for a "PDF" of this standard will face significant hurdles regarding legality, version control, and obsolescence.
In the world of mechanical engineering and precision drive technology, the connection between a shaft and a hub is critical. When high torque transmission is required without the slippage risks of a keyway, engineers turn to splines. Among the many spline standards developed globally, DIN 5482 holds a unique and important place, particularly for involute splines with a specific tooth profile.
If you have searched for the "DIN 5482 spline standard pdf," you are likely an engineer, a machinist, or a student needing to understand or manufacture a component that adheres to this German standard. Unlike its more famous relative, DIN 5480 (which covers involute splines with a reference diameter), DIN 5482 is distinct because it is based on the module system and a 30-degree pressure angle.
This article serves as a comprehensive resource. We will explore the history and scope of DIN 5482, break down its technical parameters, explain how it differs from other standards, and—most importantly—guide you on how to legitimately and responsibly obtain the DIN 5482 spline standard PDF for your engineering work.
DIN 5482 is a German standard specifying involute splines with straight-sided teeth (parallel-sided splines), commonly used for transmitting torque between shafts and hubs while allowing axial movement. It defines tooth form, dimensions, tolerances, fits, and inspection-related parameters so mating parts achieve reliable load transfer, repeatable positioning, and interchangeability.
