Collection: Woodruff Keys – Precision Half-Moon Keys for Shaft and Hub Connections
Woodruff keys, also known as half-moon keys, are used in mechanical power transmission to connect a shaft and a rotating machine element such as a gear, pulley, or coupling. Their unique semi-circular design allows them to fit into a circular keyway in the shaft, providing excellent seating, alignment, and resistance to movement or shear.
