The two charts below, “ metric ” on the left and “ inch ” on the right, provide tolerances as listed in this catalog for shaft dimensions. As an example of how to use these charts, for a 1" (25.4 mm) shaft, an acceptable h8 tolerance is -0.0013/+0" (-0.033/+0 mm). Stating differently, for a 1" (25.4 mm) bore, acceptable dimensions are 0.9987-1.0000" (25.367-25.400 mm). All dimensions are positive values unless marked. SHAFT TOLERANCES
