One New Aftermarket Replacement Woodruff Key - 7/32" x 1" (SAE)
This 7/32" x 1" Woodruff key (half-moon key) is a semi-circular shaft key used to lock gears, pulleys, sprockets, and hubs to rotating shafts, preventing independent rotation. It seats into a matching keyseat machined into the shaft and interfaces with the keyway in the mating component to transmit torque. Woodruff keys are also designed to act as a fail-safe, shearing under overload to protect more expensive drivetrain components from damage. This standard imperial size is commonly used in agricultural equipment, lawn and garden machinery, construction equipment, and general-purpose power transmission applications.
