Keyway IllustrationThe key is a machine element used to connect rotating power transmission components.  This illustration depicts common components of a keyed joint. The keyseat is the slot cut in the shaft to accommodate the key, while the corresponding slot in the component to be mounted on the shaft is called the keyway.

At its most basic explanation, the key fits into the keyseat and the keyway and is used to transfer torque from the shaft to the mounted component. Climax offers shaft collars and rigid couplings in both set screw and clamping designs that will fit a variety shaft sizes. Cataloged collars and couplings are provided with parallel keyways.
