The DIN 5462 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 While the original German standard was officially withdrawn in 1955, its specifications remain the industry benchmark for commercial vehicle transmissions and hydraulic components .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)
Step 2: Determine Centering Look for the symbol on your blueprint. If it says "DIN 5462 N 8 x 42 x 48 D", the "D" means centering on the major diameter. Your PDF will tell you that the major diameter tolerance must be ISO H7/h6, while the minor diameter is a clearance fit. din 5462 spline standard pdf exclusive
Materials and Tolerances
The DIN 5462 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.
