Side-fitting or major-diameter centering, ensuring minimal backlash and high concentricity under high torque loads. Technical Specifications and Dimensional Layout
In the dimly lit archives of the Bureau of Industrial Standards, Elias Thorne held a document that shouldn’t exist. It was a tattered, blue-bound folder labeled DIN 5462: The Exclusive Spline To the outside world,
The standard specifies the dimensions and tolerances for metric parallel spline shaft connections with straight flanks, primarily for the "light series" used in mechanical engineering. Often cited alongside ISO 14 , this standard is a cornerstone for designing high-torque connections in hydraulic pumps, truck power take-offs (PTOs), and transmission systems.

standard specifies dimensions and tolerances for straight-sided (parallel) spline shaft connections, primarily the "Light Series". It is most commonly used in heavy-duty truck hydraulics for connecting pumps and motors to power take-offs (PTOs). Key Specifications & Dimensions The standard identifies profiles by a nomenclature of [Number of Teeth] x [Minor Diameter] x [Major Diameter] .

While the official standard tables are extensive, the following provides a representative overview of the nominal dimensions defined by DIN 5462:

Parallel splines are susceptible to fretting corrosion if run dry. Always apply a high-pressure, molybdenum disulfide ( MoS2cap M o cap S sub 2
Unlike involute splines (governed by DIN 5480 ), DIN 5462 features . These splines are designed for internal centering, meaning the alignment between the shaft and the hub is maintained by the contact between the minor diameter of the shaft and the bore of the hub. Profiles : Commonly found in 6, 8, or 10-key configurations.
Internal 4-spline bores are best produced using broaching tools or wire EDM for low-volume prototyping.
When a document is labeled "exclusive," it is not a marketing gimmick—it is a legal status. The legitimate version of the DIN 5462 standard is exclusively available through authorized distributors like:
