Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Husqvarna's exact tolerances, ensuring the key seats correctly in the keyway without play or misalignment that could compromise power transfer.
- Drop-In Replacement — This key installs directly into the original keyway slot, requiring no machining or modification to the shaft or hub.
- Confirmed Fitment for FS513, FS520, and FS524 — Engineered specifically for these Husqvarna floor saws, giving you confidence that the correct part is going into your machine.
- Restored Drive Engagement — A properly fitted key locks rotating components in correct rotational alignment, restoring full power transmission between shaft and hub and preventing slippage under load.
- Protects Adjacent Components — Using an OEM-spec key prevents the uneven loading that a worn or incorrect key can transfer to shafts, hubs, and bearings, reducing the risk of secondary damage.
A key is a small but critical mechanical fastener that sits in a machined slot — called a keyway — between a shaft and a rotating component such as a pulley, sprocket, or blade hub. Its role is to lock those two parts together rotationally so that torque is transferred cleanly without slippage. When a key shears, deforms, or wears, the driven component can slip or spin freely on the shaft, resulting in loss of cutting function and potential damage to the keyway itself. Replacing a failed key promptly with a correctly dimensioned OEM part restores full drive engagement and protects the surrounding components from further wear.
