The DIN 5464 standard specifies the requirements for straight-sided splines in the heavy series, designed for both fixed and moving shaft-hub connections. This standard is critical in mechanical engineering for transmitting high torque through thin-walled hubs, as its 0∘0 raised to the composed with power pressure angle prevents hub expansion from radial forces. Key Specifications of DIN 5464
The standard provides the geometry, dimensions, and tolerances necessary for manufacturing and inspecting these heavy-duty spline connections. Designation: Straight-sided splines - Heavy series.
Current Version: DIN 5464:2010-03, which replaced the older 1965 edition. Pressure Angle: 0∘0 raised to the composed with power (straight flanks).
Centering: Typically flank-centered, though internal or diameter centering may be defined for specific applications.
Teeth Count: The heavy series features more teeth compared to DIN ISO 14, providing a significantly higher load capacity. Applications and Advantages
DIN 5464 splines are preferred in heavy-duty machinery where space is limited but torque requirements are high.
High Load Capacity: The increased number of keys/teeth allows for greater torque transmission than the light or medium series (such as DIN 5462 or DIN 5463).
Structural Integrity: Because the flanks are parallel, the forces are purely tangential. This eliminates the radial "bursting" force on the hub, allowing engineers to use low hub wall thicknesses.
Compatibility: The internal diameter gradation is consistent across the light, medium, and heavy series, often designed to be 1–2 mm larger than standard ball-bearing diameters for easier assembly. Where to Obtain DIN 5464 PDF

In the precision-driven world of mechanical engineering, DIN 5464 serves as the definitive standard for straight-sided splines of the heavy series. While "standard" may sound routine, the story of DIN 5464 is one of maximizing load capacity where lighter alternatives would fail. The Role of DIN 5464
Imagine a high-torque industrial gearbox or a heavy-duty power transmission system. To connect a shaft to a hub (like a gear or coupling), engineers often use splines—a series of parallel grooves and teeth.
The Heavy Series Difference: Unlike the more common light or medium series (such as DIN ISO 14), DIN 5464 specifies a profile with a higher number of teeth. This design allows for a much higher load capacity and ensures that torque is distributed more evenly across the connection.
The 0° Pressure Angle Advantage: The splines in this standard have a 0∘0 raised to the composed with power
pressure angle. This is critical because it prevents "hub expansion." In other words, when the shaft spins under heavy load, the force is directed tangentially rather than pushing outward, which protects thin-walled hubs from cracking or deforming. What is Inside the PDF?
The DIN 5464:2010-03 document is a concise 9-page technical guide. It provides the blueprints necessary for manufacturing these high-strength components:
Geometry and Dimensions: It defines the exact widths, depths, and counts of teeth for various shaft diameters.
Tolerances: It specifies the "fits"—how tightly the shaft and hub should slide or lock together—to ensure parts made by different manufacturers are compatible.
Centering Methods: These connections are typically flank-centered (meaning they align based on the sides of the teeth), though they can also be defined by diameter centering for extra precision. Where to Find It

standard, titled "Straight-sided splines – Heavy series," is a technical specification published by the German Institute for Standardization (DIN) that defines the geometry, dimensions, and tolerances for heavy-duty splined shaft and hub connections.
Below is an overview of its purpose, technical characteristics, and practical application. Purpose and Scope The primary function of DIN 5464 is to standardize straight-sided splines
(also known as parallel-sided splines) used in fixed and moving shaft-hub connections. Unlike the light or medium series (such as
or DIN 5463), the "Heavy Series" defined by DIN 5464 is specifically engineered for applications requiring high torque transmission through relatively thin hub walls. Technical Characteristics Pressure Angle: These splines feature a 0° flank angle The search for "din 5464 standard pdf" is
, which ensures that the torque transmission does not generate radial forces that would expand the hub. High Load Capacity: Compared to DIN ISO 14
, DIN 5464 typically specifies a higher number of teeth, which increases the total contact area and overall load-bearing capacity. Centering Methods: Connections under this standard are typically flank-centered
, meaning the torque-transmitting flanks align the parts. However, they can also be designed with diameter centering (internal or external) for higher precision. Evolution: The standard was notably updated in March 2010
(DIN 5464:2010-03), superseding the older 1965 version. The current version consists of roughly 9 pages of technical tables and requirements. Applications in Mechanical Engineering
DIN 5464 is a staple in heavy machinery and tool manufacture. It is frequently used for: DIN 5464:2010 - Straight-sided splines - Heavy series
Using data from Table 2 of the PDF:
DIN 5464 is a German standard (Deutsches Institut für Normung) that specifies the dimensions and tolerances for spline shaft connections with involute splines based on a 30-degree pressure angle.
Unlike its cousin, DIN 5480 (which covers a broader range of module and tolerance options), DIN 5464 is distinct because it focuses on number of teeth (z) rather than module as the primary defining feature. It defines a specific series of shaft and hub profiles designed for high-torque applications where a permanent or semi-permanent fixed connection is required.
As with most ISO and DIN standards, DIN 5464 is copyrighted material. It cannot be legally distributed for free on third-party blogs or file-sharing sites.

standard specifies the requirements for straight-sided splines used in both fixed and moving shaft-hub connections. Unlike standard series, the "heavy series" defined here features a higher number of teeth, which significantly increases load capacity compared to the general DIN ISO 14 standards. Key Technical Features: 0° Flank Angle:
This design prevents the hub from expanding under radial forces, making it exceptionally stable for high-torque applications. Centering Options:
While typically flank-centered, these connections can also utilize additional diameter centering for higher precision. Geometry and Tolerances:
The standard provides 9 pages of detailed geometric data and associated tolerances necessary for manufacturing and quality control. Why the Heavy Series Matters Choosing DIN 5464 over standard profiles like DIN ISO 14
is usually a matter of wall thickness and force. Because the flank angle is zero, the radial component of the flank force is eliminated. This allows engineers to use hubs with thinner walls without risking structural failure under high loads. Where to Access the DIN 5464 PDF

In the world of mechanical engineering, failure often begins at the connection points. While bolts and screws are common, the true heavy lifters of torque transmission are splined connections. Among the various standards governing these critical components, DIN 5464 stands out as a benchmark for high-load, fixed shaft-hub connections.
As industries digitize their technical libraries, the search for the "DIN 5464 standard PDF" has become a routine task for engineers and procurement officers. However, finding the document is only the first step; understanding the geometric precision it dictates is where the real engineering begins.
Manufacturers use go/no-go plug gauges and double flank rolling testers to verify splines. The tolerances for these gauges are also specified in Annex A of the DIN 5464 standard.
