Below are technical reference charts for our standard keys All dimensions are given in inches The key numbers indicate nominal key dimensions. Woodruff key sizes, dimensions and tolerances are given in the following chart according to asme b17.2 standard

Woodruff key is almost in semicircular disk shape with uniform thickness and it's a demountable machinery part that provides means for transmitting torque between the shaft and hub. The height of a woodruff key is less than half its nominal diameter Distance below center is the distance from the nominal diameter centerline to the top of the woodruff key. Woodruff keys are of semi circular disc shaped which completely fits into the semi circular pocket or circular recess provided in the shaft and which has been machined by a woodruff keyway cutter to give a good fit / tight fit to push the key into the recess.
