A (internal spline) is a cylindrical component with teeth cut into its inner bore, designed to mate with a matching external spline shaft. The DIN 5482 spline bus is typically used in heavy machinery, automotive steering systems, and hydraulic pumps where high torque transmission and axial positioning are required. 2. Key Characteristics of DIN 5482 | Feature | Specification | |---------|----------------| | Pressure Angle (α) | 30° | | Fit Type | Major diameter fit (centering on the major diameter) | | Module Range | 0.5 mm to 2.5 mm (preferred) | | Tooth Profile | Involute | | Tolerance System | Based on major diameter and side fit classes | | Standard Status | Withdrawn (replaced by DIN 5480 in new designs), but still used in legacy and repair applications | 3. Dimensional Data (Example for Common Sizes) Below are typical nominal dimensions for a DIN 5482 spline bus (internal) – module m = 1.0 mm , number of teeth z = 24 .
For new applications, switching to DIN 5480 or ISO 4156 is recommended. For replacement parts, exact dimensional verification from original standards or sample measurement is essential.

Report ID: MEC-DIN5482-001 Subject: Dimensional characteristics, material requirements, and application of the DIN 5482 internal spline bus. Date: [Current Date] 1. Introduction The DIN 5482 standard (Deutsches Institut für Normung) defines involute splines with a 30-degree pressure angle and a module series based on the reference diameter . Unlike the more common DIN 5480 (which uses a side-fit system), DIN 5482 is an older but still widely used standard for major diameter fit splines. A (internal spline) is a cylindrical component with
