Therefore, this criterion applies only when the fit surface has a width sufficient as a reference face. 3 When determining a tolerance for permissible form accuracy, the reference dimensions used are shaft diameters da and db. For example, when using a JIS class 5 bearing for a dia. 50 mm shaft, the tolerance of roundness is
