: The flanks are perfectly parallel to the radial line. This eliminates radial separation forces and prevents hub expansion under load.
: The high surface area contact makes it highly resistant to wear under shock loads, rapid reversals, and high-frequency alternating torques.
The standard document outlines the design requirements, dimensions, and tolerances for straight-sided splines within the heavy series . Published by the Deutsches Institut für Normung (DIN) , this engineering standard establishes a uniform framework for fixed and moving shaft-hub connections that must withstand extreme operational stresses. Producing components to the DIN 5464 standard requires

Unlike lighter profiles, the heavy series maximizes the number of teeth relative to the shaft diameter. This design choice increases the total contact surface area, which optimizes surface pressure distribution. Mechanical Principles 0∘0 raised to the composed with power
: Unlike the more common light or medium series (such as DIN ISO 14), DIN 5464 specifies a profile with a higher number of teeth. This design allows for a much higher load capacity and ensures that torque is distributed more evenly across the connection.
