DIN 5462 splines are not historical curiosities; they are alive and well in countless machines. Their primary domain is and direct-mounted hydraulic pumps in commercial vehicles and agricultural machinery. This standard is a common choice for connecting a truck's transmission to auxiliary equipment like hydraulic pumps for dump trucks, cranes, and concrete mixers.
Because DIN 5462 has been superseded, the most practical approach for most engineers is to acquire or the international ISO 14:1982 standard. These documents provide the same dimensional specifications as DIN 5462, along with updated tolerances, verification methods, and gauging requirements. DIN ISO 14 remains an active, purchasable standard and is the appropriate reference for new designs.
A crucial design aspect of DIN 5462 connections is . In this configuration, the hub is centered on the shaft's outer diameter. This ensures that the two components are precisely concentric, which is essential for high-speed rotating machinery where even minor misalignment could lead to vibrations, premature wear, or failure. din 5462 spline standard pdf exclusive

DIN 5462 is a standard published by the German Institute for Standardization (DIN) that defines the requirements for splines with a specific profile, known as "evolution splines" or " involute splines". This standard covers the following aspects: Because DIN 5462 has been superseded, the most
Used as the male drive shaft for heavy-duty dump truck pumps, axial piston pumps, and bent-axis motors (e.g., Rexroth, Parker, or Sunfab styles).
