The Husqvarna 543080916 Bearing is a genuine OEM replacement component designed for the FS309 floor saw. As a factory-original part, this bearing is manufactured to Husqvarna's exact tolerances, ensuring the smooth, low-friction rotation that the FS309 depends on during demanding slab-cutting work. DHS Equipment supplies this part to help keep your floor saw running at full capacity.
Key Features
- OEM Precision Tolerancing — Manufactured to Husqvarna's exact dimensional and load specifications, this bearing delivers the tight tolerancing that rotating assemblies require to function correctly under the sustained stress of floor sawing.
- Drop-In Replacement Fit — Engineered to match the original mounting dimensions of the FS309, this bearing seats correctly without rework or modification to surrounding components.
- FS309 Floor Saw Compatibility — Confirmed fitment for the Husqvarna FS309 floor saw, so you can cross-reference part number 543080916 against your parts diagram with confidence.
- Restored Rotational Performance — A worn or failed bearing causes excessive vibration, heat buildup, and accelerated wear on adjacent components. Replacing it with this OEM part restores smooth, low-friction operation and protects the surrounding assembly.
- Genuine Husqvarna Quality — Sourced directly from Husqvarna's OEM supply chain, this part meets the same standards as the original component fitted at the factory — no guesswork on material grade or load rating.
A bearing supports rotating shafts and moving components by reducing friction between the moving part and its housing, allowing the machine to transfer power efficiently while minimizing heat and wear. In a floor saw like the FS309, bearings are critical to keeping the blade drive and other rotating assemblies turning smoothly under the heavy loads generated by concrete cutting. When a bearing begins to fail, it typically produces grinding noise, increased vibration, or excessive heat — warning signs that, left unaddressed, can lead to damage of the shaft, housing, or surrounding drivetrain components.
