What is a Woodruff key?


Keys are mechanical parts used to link two rotating components, such as a shaft and a pulley or gear, in order to transmit movement or torque.

Keys come in different shapes and sizes: a semi-circular "half-moon" shape as in Woodruff keys, straight like parallel keys, or tapered like gib-head keys.

Keys are essential in many industries to guarantee reliable, long-lasting connection between mechanical components.



Woodruff keys are essential mechanical parts used for transmitting torque between a shaft and a hub. These keys are made according to DIN 6888 and NFE 22179 standards.

Woodruff keys are mainly used in applications with low torque. Thanks to its shape, Woodruff keys are easier to insert or remove than conventional straight keys, making it useful for transmission applications.

DIN 6888 - NFE 22179 standards


German DIN 6888 and French NFE 22-179 standards guarantee that these keys are compatible with industrial systems.

Woodruff keys have a dimensional tolerance of h9 to h11 (tolerances for shaft and fit).
