Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's original dimensional and material specifications, delivering the structural integrity expected of a load-bearing hub component.
- Direct-Mount Replacement — Engineered to align with existing mounting points and mating components on the FS-series drive system, allowing straightforward installation without modification.
- Broad FS-Series Compatibility — Confirmed fitment across multiple Husqvarna floor saw models, including the FS4800D, FS5000D, FS6600D, FS6800D, FS7000D, FS7000DL, FS7000DMT, FS8400D, and FS5000.
- Restored Drive Integrity — A correctly fitted hub maintains precise blade-shaft concentricity, which is essential for straight, accurate cuts in concrete and asphalt slabs.
- OEM Part Number Accuracy — Ordering by part number this part ensures you receive the correct hub variant for your specific floor saw configuration, eliminating costly mis-fit returns.
The hub is a central structural component in the blade drive assembly of a walk-behind floor saw. It connects the drive shaft to the blade flange, transmitting rotational force while keeping the cutting blade accurately centered and rigidly secured during operation. A worn, cracked, or damaged hub can cause blade wobble, uneven cutting depth, and accelerated wear on surrounding drive components — making prompt replacement essential for maintaining cut quality and operator safety on slab-cutting applications.
