Frequently Asked Questions
What does the DIN 6885 Parallel Key Calculator do?
It calculates DIN 6885 parallel key and keyway dimensions from shaft diameter, including key width, height, keyway depths, tolerance fits, and applicable key length ranges.
How do I use it?
Enter the shaft diameter, then select a listed key size. The calculator returns the corresponding DIN 6885 dimensions, fits, and standard length range.
What does the Keyway Strength Calculator do?
It calculates shear and bearing stresses on the key, shaft keyway, and hub keyway for a given torque. It also computes the minimum required key length and compares it to the selected standard length.
Is it free?
Yes. This Kod5 calculator runs in the browser, requires no installation, and is free to use.
