DIN 5480 standard governs involute splines based on reference diameters, primarily used for high-precision torque transmission in mechanical engineering. Unlike ISO 4156, DIN 5480 allows the reference diameter to be independent of the module, making it easier to match splined components with standardized ball or roller bearings. d2t1xqejof9utc.cloudfront.net Core Geometric Specifications The standard specifies a 30° pressure angle
