Din 5480 Spline Dimensions Pdf Verified May 2026

The defines the dimensions and tolerances for involute splines based on reference diameters, ensuring high torque transmission and precise centering. Unlike other standards, it is designed so that the reference diameter often matches standard ball or roller bearing bores to allow for easier assembly and slip-fitting of components. Understanding the DIN 5480 Designation

Range from 5 (most precise) to 12 (least precise). din 5480 spline dimensions pdf verified

): Used to adjust the spline to the reference diameter. It typically ranges from for shafts. The defines the dimensions and tolerances for involute

A standard DIN 5480 callout follows a specific syntax that defines all necessary geometric properties: Description W / N Shaft / Hub W (Welle) for external shaft; N (Nabe) for internal hub. 120 Reference Diameter ( dBd sub cap B The nominal size, often matching bearing bore diameters. 3 The size of the tooth, ranging typically from 0.5 to 10. 38 Number of Teeth ( The total count of teeth on the circumference. 8f Tolerance Class & Fit ): Used to adjust the spline to the reference diameter

for hobbing, but can vary by manufacturing method (e.g., 0.55m for broaching). Profile Shift (

Letters a–g are slip fits; h is a "line-on-line" fit; j–v are interference fits.
