Key & Keyway Size Chart

Look up a selected manufacturer's key size for a shaft range. Available dimensions retain their product family and documented range boundaries.

How to use this data

Locate the shaft diameter within the published product range (lower,upper]. The key's width/height is a dimensional selection; obtain the actual shaft/hub keyway drawing for machining.

  • Shaft ranges use exclusive lower and inclusive upper boundaries.
  • Dimensions are the selected product family, not a full DIN tolerance standard.

CHECK THE METHOD

Worked example

20 mm shaft is in(17,22]mm and maps to the selected 6×6 mm key cross-section.

Common lookup questions

Which range owns a 22 mm shaft?

The(17,22]range owns 22 mm. Diameters greater than 22 mm move to the next range; boundary values are not duplicated.
