NEMA has developed standards over the years for shaft diameters based on motor frame sizes. When doing a Design Flexibility Analysis, use these shaft diameters

The following table shows recommended shaft and housing sizes and tolerances for different applications. It is assumed that bearings used are ABEC 5 tolerance (+0 -.0002 inch) for bore and O.D. If a different grade of bearing is used, this will affect recommended dimensions of mating components. Low speed, or spring preload.

The following tables are a guide for establishing shaft and bearing fits for miniature and instrument bearings, when the expansion coefficients of the shaft and housing are similar or when the operating temperature differential between them is nominal. In other conditions, modification in fits and internal clearance may be required. Shaft Fits

For example, standard NEMA frame dimensions, which have been revised only once since 1950, still specify much larger shaft sizes than commonly accepted
