The DIN 5482 standard defines the dimensions, profiles, and manufacturing tolerances for involute splined joints. Splines are ridges or teeth on a drive shaft that mesh with slots in a mating piece to transfer torque. Key Characteristics

DIN 5480, introduced in the 1980s–1990s, marked a fundamental philosophical shift: instead of selecting from tables based on available space, engineers start from actual load conditions—torque to be transmitted, allowable flank pressure, material properties—and compute optimal dimensions. This modern approach demands CNC equipment but produces lighter, more efficient, precisely load-matched connections.
