Key Features
- Genuine OEM Specification — Manufactured by Husqvarna to the exact dimensional tolerances required for secure shaft-to-hub keying, ensuring no play, slippage, or misalignment in the drive assembly.
- Direct Drop-In Replacement — Machined to match the original keyway profile, this key seats fully without filing, shimming, or modification to the shaft or hub.
- Broad FS-Series Compatibility — Fits the FS4800D, FS5000D, FS5000, FS7000D, FS7000DL, FS7000DMT, and FS8400D walk-behind floor saws in a single part number.
- Torque Transfer Integrity — A correctly fitted key maintains positive torque transfer between the shaft and rotating component; a worn or sheared key causes slippage, uneven blade drive, and accelerated wear on both mating surfaces.
- Operational Safety — On high-load floor saw applications, a failed or missing key can cause sudden loss of drive engagement. Using a genuine OEM key maintains the mechanical integrity of the drive system.
A key is a small precision component that locks a rotating shaft to a hub, pulley, or gear, ensuring both parts turn together as a single unit under load. In a walk-behind floor saw like the FS4800D or FS7000D, the key transmits cutting torque through the drive train — if it shears or works loose, the shaft spins freely inside the hub, causing immediate loss of drive and potential damage to the keyway itself. Replacing a worn or damaged key promptly with a correctly dimensioned OEM part protects the surrounding components and restores full power transmission to the blade system.
