As a direct Husqvarna OEM component, this key is manufactured to the exact specifications required for proper fit and function within the drivetrain or shaft assembly. DHS Equipment supplies this part to help keep your floor saw operating as intended — cross-reference part number 542020055 against your parts diagram to confirm the correct application before ordering.
Key Features
- Genuine OEM Construction — Manufactured by Husqvarna to exact dimensional tolerances, ensuring the key seats fully and transmits torque without slippage or premature wear.
- Direct Drop-In Replacement — Engineered to match the original keyway geometry on the FS3500E, allowing straightforward installation without modification.
- FS3500E Floor Saw Compatibility — Specifically sourced for the Husqvarna FS3500E floor saw; verify fitment using part number 542020055 and your machine's parts diagram.
- Torque Integrity Restored — A correctly fitted key locks rotating components — such as pulleys, sprockets, or blade drive shafts — securely to their shafts, maintaining full power transfer and preventing component movement under load.
- Compact but Critical — Although small, this component plays a direct role in shaft-to-hub engagement; a worn or missing key can result in slipping, vibration, and accelerated damage to surrounding drivetrain parts.
A key is a small precision-machined component that fits into a machined slot — called a keyway — between a shaft and a hub, pulley, or sprocket. Its role is to lock the two parts together rotationally so that torque is transferred evenly without slipping. When a key is sheared, worn, or missing, the connected component can spin independently of the shaft, leading to loss of drive, vibration, and damage to the keyway itself. Replacing a damaged key promptly with the correct OEM part restores full mechanical engagement and prevents further wear to surrounding components.
