The following notes indicate how to calculate a reasonable value for the stress resulting from an c = Key Chamfer size (m); t1 = Depth of keyway (m) 

Keyways will be furnished per ISO/R773 and Js9 width tolerance unless otherwise specified. (Dimensions comply with DIN 6885/1) † Requires the use of chamfered keys. Surface Finish — Sides and bottom of keyways shall not exceed 250 micro inches. See Page 2 for Optional P9 & D10 Keyway Dimensions H W R T2 T=D+T2 T D ®

In this calculation a shaft of length L , diameter D , with keyway dimensions K × H is considered. The shaft is under torque T , applied to the end. As a result 

07/05 · In the following section you will find information on British standard keyway and bore sizes. John Kings will generally bore all wheels to a H7 tolerance unless specified by the customer. All wheels will come with grub screw fixings over keyways and at 90 degrees as standard. The standard positioning for all keyways will be in line with a tooth. []

It is also possible to make a calculation of frictional press-fitting, which transmit torque by frictional forces. In this calculation, a connection with a prismatic key with a length L , height H
