Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's exact material and dimensional specification, ensuring the key seats and locks as intended with no compromise in fit or retention.
- Direct Drop-In Replacement — Replaces the original component on compatible floor grinders without modification, slotting directly into the keyway on your shaft or drive assembly.

- Positive Drive Transfer — A correctly fitted key locks the rotating component to the shaft, maintaining positive torque transfer and preventing slippage that can cause premature wear or erratic machine behavior.

A key is a small precision component that sits in a machined slot — the keyway — between a shaft and a rotating part such as a drive hub, pulley, or sprocket. Its role is to lock the two components together rotationally so that torque is transferred from the shaft to the driven part without slipping. When a key shears, deforms, or goes missing, the driven component can spin freely on the shaft, causing loss of drive, accelerated wear to the keyway, and potential damage to surrounding assemblies. Replacing a worn or failed key promptly with the correct OEM part restores full, positive drive engagement and protects the integrity of the shaft and hub.
