Note: Be aware that some online resources may provide legacy information or "similar" technical drawings, but for official engineering design, a certified copy is recommended. Why Adhere to the DIN 5482 Standard?
: Identifies the part as an external spline (Shaft). An N denotes an internal spline (Hub).
Unlike its successor (DIN 5480), which uses module-based sizing, DIN 5482 uses a specific sizing convention (e.g., ) that is not directly compatible. 📏 Key Technical Specifications

For those interested in accessing the DIN 5482 standard, it is available in PDF format from various sources, including:
Machine shops need the exact legacy tolerances to manufacture replacement shafts and gears.
The DIN 5482 standard provides several benefits to manufacturers and users of involute splines, including: Note: Be aware that some online resources may
denotes an external spline profile (shaft / male connection). First Number (40): The approximate major diameter ( ) in millimeters. Second Number (36): The approximate minor diameter ( ) in millimeters.
When a standard is withdrawn, standardisation bodies stop updating it, but industry usage rarely disappears overnight. The hunt for the DIN 5482 PDF persists for several practical reasons: 1. Maintenance of Legacy Machinery
If you work in mechanical power transmission or precision engineering, you’ve likely encountered the term An N denotes an internal spline (Hub)
The following parameters define any involute spline and are essential for proper design:
The tooth profile distributes stress evenly across the contact area.
): The theoretical diameter where the tooth thickness equals the space width. Major Diameter (
The DIN 5482 standard is a widely referenced German engineering specification for involute splines with a 30-degree pressure angle. Although the standard was officially deactivated and replaced by DIN 5480, it remains a critical legacy specification in mechanical engineering, automotive design, and industrial manufacturing. Millions of existing machines, gearboxes, and hydraulic pumps worldwide still rely on DIN 5482 connections.
