Frequently manufactured from or high-strength alloy steels for torque transmission
When integrating a DIN 5462 interface into your machinery, observe the following best practices:
Many mechanical engineering suppliers (e.g., OmniGear) provide data sheets summarizing the DIN 5462 standard dimensions. Important Notes on the Standard din 5462 spline standard pdf exclusive
The standard specifies the dimensions for straight-sided (parallel) metric spline shaft connections, specifically the 8 x 32 x 36 profile commonly used in hydraulic pump and power take-off (PTO) applications . While the original German standard was officially withdrawn in 1955, its specifications remain the industry benchmark for commercial vehicle transmissions and hydraulic components . Key Specifications for DIN 5462 (8 x 32 x 36)
): The inner centering diameter, standardly set at (with tight tolerances like for the hub and for the shaft). Major Diameter ( ): The outer tip diameter, standardly set at 36 mm . Tooth Width ( Key Specifications for DIN 5462 (8 x 32

Power Take-Off (PTO) gearboxes mounted to truck transmissions frequently use a DIN 5462 4-bolt, 4-spline output interface.
| Feature | Detail | |---------|--------| | Standard type | National (Germany), but widely used in Europe | | Current version | DIN 5462:1976-07 (still active, though superseded for new designs by DIN 5480) | | Spline type | Straight-sided (parallel-sided) | | Centering | Typically on the (shaft → hub bore) | | Load capacity | Light to medium | | Common applications | Agricultural machinery, conveyors, manual gearboxes, older machine tools |
DIN 5462 (or its replacement, DIN ISO 14) is appropriate for and for applications where the simplicity of a straight-sided spline is preferred. For new designs, DIN 5480 (involute splines) is generally recommended due to its superior load distribution and manufacturing flexibility.
Manufacturing DIN 5462 splines requires specialized machining processes to ensure dimensional accuracy and proper fit:
