Woodruff Key
Woodruff keys are semi-circular, disk-shaped components used to securely attach gears, pulleys, or other machine parts to a shaft. These keys fit into a specially shaped slot, known as a keyway, which is machined into the shaft. A Woodruff key is partially recessed into a keyway on a shaft, with its semi-circular shape allowing it to sit slightly above the surface. This design helps prevent axial or rotational movement of the attached component, ensuring efficient torque transmission. Woodruff keys are particularly useful in applications with limited space, as they do not protrude far from the shaft. They are commonly used in automotive, industrial, and machinery applications where precise and reliable connections are required. Available in various sizes, Woodruff keys are made from high-strength materials like steel to ensure durability and resistance to wear. Their ability to provide secure engagement in compact spaces makes them essential in many mechanical assemblies.
