Keys and keyways are used to transfer torque from shafts to holes or vise versa. As a general rule, the key is a tighter fit to the shaft so that the key 

Source #2: press fit tolerance chart Maintenance Practice Question EASA PART 66 GUIDE In this system, shaft gets the letter h and the hole gets a different letter o which decides the position of the tolerance zone to obtain desired fit The shaft tolerance should be (-), in relation to the maximum shaft size, to prevent the shaft from being to

The higher this number is the tighter the tolerance of the bearing and the better the degree of precision of the bearing.
