DIN 5463 is a fundamental standard for designing robust metric parallel spline connections. By adhering to the dimensions and tolerances specified in a , engineers can ensure that their shaft and hub connections are durable, properly aligned, and interchangeable with standard components.
A spline designation like indicates: 8: Number of teeth (n) 46: Inside Diameter (d₁ in mm) 54: Outside Diameter (d₂ in mm) Key Dimensions to Consider (Medium Series):

The standard specifies the dimensions, tolerances, and design requirements for metric parallel spline shaft connections . Originally published in 1955, it has largely been superseded by the international standard ISO 14 , though it remains a common reference in industrial catalogs and technical drawings for "medium series" straight-sided splines.

The purpose of DIN 5463 is to ensure that keys and keyways are designed and manufactured to a standard that ensures:
Compared to involute splines (like DIN 5480 or ANSI B92.1), parallel splines transfer less torque for the same shaft diameter. How to Find and Use a DIN 5463 PDF DIN 5463 is a fundamental standard for designing
