Hub keyway depth is one-half the nominal height of the key and measured from the side corner. The dimension from the top of the keyway to the opposite bore side, "T-dim", is calculated from (refer to ANSI/AGMA 9002-B04) the following: T = bore + (h kw - Ch) Created Date:

Metric Key & Keyway Dimensions Per ISO/R773 - Js9 Width Tolerance « + Keyways will be furnished per ISO/R773 and Js9 width tolerance unless otherwise specified. (Dimensions comply with DIN 6885/1) † Requires use of chamfered keys. Surface Finish — Sides and bottom of keyways shall not exceed 250 micro inches.

A shaft key is a small metallic component mounted between the shaft and hub to restrict the relative motion. Keyway is a recess in the shaft and hub to accommodate the shaft key. Keys are inserted inside the shaft and hub keyway to ensure the working of the complete system. Set screws and pins can also work as an alternative to the keyed joint

As noted above, when selecting a keyway tolerance, there are two common selections in the metric system. The first is Js9. This is a +/- band 

When the key is of an appropriate size relative to the torque to be transmitted, a shaft thicker than the applicable shaft diameter may be used.

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

11/13 · For a solid steel shaft of 18mm diameter, with keyway 6 wide x 32 long by 3.5 deep: T = (390 x 10 6 * 0.018 * 0.032 * 0.0035) / 2. T = 393.1 Nm. In this case, the torque that can be transmitted when a key is added to the shaft is approximately 12 percent lower than the torque that can transmitted by the plain shaft (393 Nm vs 447 Nm).
