🔌 Function

Sits in the keyway between shaft and hub so the drive is taken on the key and the two turn together without slipping.

⚠️ Common Signs of Failure

• Drive slipping or the driven part not turning with the shaft
• Rhythmic tapping or knocking from the drive
• Key found sheared, rolled or partly out of its keyway
• Keyway mouth battered or opened out
• Hub able to rock on the shaft with the fixing slack

🛠️ Service Notes

• Check both keyways before fitting a new key — a sheared key almost always leaves damage behind it
