It also calculates the required length of the key to carry a given load, and gives exact limit dimensions of what the initial shaft keyway must be to achieve a certain post-grind dimension. 030: 0. In some cases, t1 and t2 should be adjusted so that a side of the key will come into uniform contact with the shaft and the hub. Metric keyways are dimensioned by width and depth as measured from the radius of the shaft to the center of the keyway. 2 16 45 12 19 - + n 19 n 25 28 - 0. 5 SHAPE, DIMENSIONS AND TOLERANCES OF KEYWAYS 8 -4 X Sect ion X-X Detail A Vaiues in millimetres Shaft Keyl ) Keyway Diameter d Width b Depth*) Sect ion bXh Radius r Tolerante for class fit Free Normal Close Shaft tl Shaft Hub Hub and hub H9 DIO IV9 Js9 P9 nom.
