Scope

This document provides the data and indications necessary for the design and manufacture of straight (non-helical) side-fitting cylindrical involute splines. Limiting dimensions, tolerances, manufacturing deviations and their effects on the fit between connecting coaxial spline elements are defined in the formulae and given in the tables. Unless otherwise specified, linear dimensions are expressed in millimetres and angular dimensions in degrees.
