Frequently Asked Questions

How to install woodruff keys?

  • Woodruff keys should be installed on the hub's low side.
  • The key will rock in the keyway during installation, allowing a tight fit.
  • If the key is installed on the hub's high side, it will catch, resulting in improper installation and the risk of damage to the assembly.

What standards do these machine keys comply with?

ANSI B17.1 and DIN 6888.
