Woodruff Keys

Woodruff keys come as square, rectangular, or semi-circular shapes, depending on the application. It makes it possible for the shaft to be connected to the working gear with less torque. Keys serve as a fail-safe, or sacrificial, device to ensure that gears are not damaged in the event of jamming; they will break or shear before gears suffer damage.
