The Husqvarna 543044796 Key is a genuine OEM replacement designed for the FS400LV and FS600E floor saws. As a factory-original component, this key ensures correct engagement between rotating shaft and drive components, maintaining the precise alignment these machines depend on during demanding slab-cutting work. DHS Equipment supplies this part to help keep your floor saw performing at full capacity.
Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's exact material and dimensional specifications, ensuring the correct fit between mating shaft and hub components without play or slop.
- Exact Shaft-to-Hub Fit — Engineered to drop directly into the keyway slot as designed, maintaining proper torque transfer from the drive shaft to the driven component.
- Confirmed Floor Saw Fitment — Compatible with the FS400LV and FS600E floor saws; cross-reference 543044796 against your parts diagram before ordering to confirm the correct application.
- Restored Drive Integrity — A worn or sheared key allows shaft-to-component slippage, which disrupts blade drive and can cause rapid secondary wear on the keyway itself; replacing with this part restores solid, slip-free power transfer.
- Protects Adjacent Components — Using the correct OEM key prevents overloading the keyway, protecting the shaft and hub from the accelerated wear that an incorrectly sized key causes over time.
A key is a small hardened component that sits in a machined slot — called a keyway — cut into both a shaft and the hub of a driven component such as a pulley, sprocket, or blade arbor. It locks the two parts together so that torque from the engine or motor is transmitted without slippage. When a key shears or wears, the driven component can spin freely on the shaft, immediately halting effective power transfer and risking damage to the keyway itself — making prompt replacement essential to restoring full machine function.
