The key length should be less than about 1.5 times the shaft diameter to ensure a good load distribution over the entire key length when the shaft becomes twisted when loaded in torsion. We've put together a keyway cheat sheet in metric, so you can be sure you have the right width and depth for your application. The keyway dimensions are also different from the english system
Metric keyways are dimensioned by width and depth as measured from the radius of the shaft to the center of the keyway.
+ keyways will be furnished per iso/r773 and js9 width tolerance unless otherwise specified (dimensions comply with din 6885/1) † requires use of chamfered keys. The document provides standard dimensions for keys and keyways in both metric and imperial units Tables show the nominal shaft diameter range, key size, and dimensional specifications for the key and keyway (dimensions a through f)
Keys can be either rectangular or square, and specifications cover shaft diameters from 10mm to 150mm in metric, and 1/4 to 6 in imperial units Learn everything about keyway dimensions, types, tolerances, design, and how to calculate keyway depth and width with formulas and standard keyway size charts for accurate mechanical design. A comprehensive overview of keyways, how they function, and the key and keyway dimensions/sizes involved in their design. The dimensions of the part, required by the design criteria (strength, rigidity, wear resistance etc.) corresponding to the accepted design scheme, are determined
Finally the drawing of the part is made indicating all dimensions, accuracy of manufacture, surface finish and other information necessary for the manufacture of the part.

Load distribution factor for splines km the load is equally distributed if the transferring load is purely radial torsion and the torsional radial load is in the middle of the spline length But if, for example, a bevel gear is used, this will put some unwanted axial loads into the spline. Determine correct dimensions for a keywayanother excellent b You must enter at least 2 items shaft diameter (in)
You must enter at least 2 items shaft diameter (d) = key width (k) = key height (h.
Home > knowledge base > standard keyway dimensions standard keyway dimensions The keyway calculator is a valuable tool that simplifies the complex process of calculating keyway dimensions It helps engineers and designers determine the width and depth of keyways needed for specific applications. In conclusion, keyways are vital components in mechanical systems, playing a crucial role in torque transmission and load distribution
Understanding the various types of keyways—standard, metric, woodruff, splines, and custom solutions—is essential for engineers and designers who aim to enhance the reliability and efficiency of their.
