The "heavy duty profile" designation indicates that the spline teeth are designed to withstand higher bending stresses and surface pressures than standard machine splines (like DIN 5463).

Involute splines (a different tooth profile altogether). Accessing the DIN 5464 Standard PDF

series, allowing it to transmit significantly higher torques. Centering Methods: These connections are typically flank-centered , but can also be defined by additional diameter centering. Mechanical Advantage: Do not download "free DIN 5464 PDF" from

The DIN 5464 standard establishes the geometric profiles and tolerances necessary for the interchangeability of splined shafts and hubs. While less common today than the involute splines defined by standards like DIN 5482 , DIN 5464 remains a critical reference for maintaining legacy equipment or specific heavy-duty industrial applications. Features four parallel-sided (straight) keys.

The standard specifies the requirements for straight-sided splines belonging to the heavy series . Published by the German Institute for Standardization (Deutsches Institut für Normung), this standard is essential for engineers and manufacturers designing robust shaft-hub connections capable of transmitting high torques. Overview of DIN 5464 When connecting a shaft to a hub, the

Because the heavy series can handle significantly higher loads, it is frequently used in: For power take-off (PTO) shafts.

The primary advantages of spline connections include:

Do not confuse DIN 5464 with DIN 5463 (hexagon socket set screws with cone point) or DIN 5466 (torque control for hexagon socket fasteners). DIN 5464 is specifically about the drive geometry for reduced-head screws.
