In this paper, about planar multilink path generators consisting of revolute pairs, describing links and radial clearances at revolute pairs by vectors, the analysis of output errors at the generated points is carried out.Moreover, describing link lengths and diameters of holes and shafts by random variables, the optimum tolerances of link lengths and pairing elements are determined as tolerances that make the output errors minimum and uniform at the generated points over the full ranges of input motions.As a practical example of planar multilink path generators, the optimum tolerances of link lengths and pairing elements of the planar six-link path generator are determined.
