Tolerances for tapered seats for rolling bearings. To determine the permissible dispersion of the taper angle α, use α = 2atan (V k /2); The roundness tolerance is defined as 'distance t between two concentric circles in each radial plane perpendicular to the cone axis along the tapered surface of the shaft'. t is the value of tolerance grade IT5/2, based on the diameter d.
