Standard Sizes of Transmission Shafts The standard sizes of transmission shafts are:25 mm to 60 mm with 5 mm steps; 60 mm to 110 mm with 10 mm steps ; 110 mm to 140 mm with 15 mm steps ; and 140 mm to 500 mm with 20 mm steps. The standard lengths of the shafts are 5 m, 6 m and 7 m. Page 1of11.

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

Calculate Standard Shafts and Keyways We built a calculator to determine the standard keyway based on your shaft diameter, either in inches or millimeters. Shaft Diameter (inches) Shaft Diameter (mm) Milling & Broaching Custom Keyway Widths There's always the option of increasing the width of the keyway beyond the width of the end mill.

The most widely followed dimensions for propeller tapers is the internationally accepted standard S.A.E. taper dimensions which is 1 in 16 up to and including 5 

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.
