    Woodruff & Straight Keys

    A Woodruff key is a semicircle-shaped machine key that prevents gears, hubs or other components from moving independently of a rotating shaft or spindle. They are used to improve concentricity of the shaft and the mating part, helping to bear the load during high-speed operations. They also act as a fail‑safe that protects expensive parts by shearing under excessive loads.
