The Husqvarna 521963301 Blade Bushing is a genuine OEM replacement designed for the FS4600G floor saw. As a factory-original component, this bushing is manufactured to Husqvarna's exact tolerances, ensuring a true drop-in fit without modification. DHS Equipment supplies this part to help keep your FS4600G floor saw running at full capacity.
Key Features
- Genuine OEM Precision — Manufactured to Husqvarna's exact bore and diameter tolerances, ensuring the blade seats and spins with the same concentricity as the original component.
- Direct-Fit Replacement — Engineered to match the original mounting interface on the FS4600G, installing directly into the blade arbor assembly without reworking or adapting surrounding components.
- FS4600G Floor Saw Compatibility — Specifically validated for the FS4600G floor saw, so you can cross-reference part number 521963301 against your parts diagram with confidence.
- Restored Blade Stability — A correctly fitted bushing maintains proper blade centering under load, supporting consistent, straight cuts through concrete and asphalt surfaces.
- Operational Safety — A worn or oversized bushing can allow blade wobble at speed, creating a hazardous condition. Replacing with a genuine OEM part restores the correct blade-to-arbor fit and reduces that risk.
The blade bushing serves as the precision interface between the diamond blade and the saw's arbor shaft. It centers the blade on the spindle and transfers rotational force evenly, keeping the blade tracking true during cutting. When a bushing wears, becomes deformed, or is incorrectly sized, the blade can run off-center — leading to uneven cutting, accelerated blade wear, vibration, and unsafe operating conditions. Replacing this component with a genuine Husqvarna part restores the correct fit and keeps the FS4600G performing to its designed specification.
