The Husqvarna 505573202 Blade Shaft is a genuine OEM component designed for the X390 early entry saw. As a direct factory replacement, this blade shaft meets Husqvarna's original engineering specifications, ensuring proper blade seating, concentricity, and drive engagement. DHS Equipment supplies this part to help keep your equipment running at full capacity on green-concrete cutting applications.
Key Features
- OEM-Matched Shaft Geometry — Manufactured to Husqvarna's original dimensional specifications, ensuring correct blade centering and concentricity that aftermarket alternatives may not replicate.
- Direct Drop-In Replacement — Engineered to the same tolerances as the original, this blade shaft seats and connects to existing drive components without modification to surrounding assemblies.
- Confirmed Fitment for the X390 — Designed specifically for the X390 early entry saw, so you can cross-reference part number 505573202 against your parts diagram with confidence.
- Restored Blade Stability — A worn or damaged blade shaft causes blade wobble, uneven cuts, and accelerated wear on arbor-side components. Replacing it restores clean, accurate cuts from the first pass.
- Structural Durability — Built from materials selected for the rotational loads and vibration demands of early-entry concrete cutting, supporting consistent performance through demanding pour schedules.
The blade shaft is the central rotating component that transfers power from the saw's drive system directly to the cutting blade. It holds the blade in precise alignment and maintains concentricity under the high rotational speeds required for early-entry green-concrete cutting. When a blade shaft is worn, bent, or damaged, the result is blade runout — causing rough, inaccurate cuts, increased stress on bearings, and potential blade security issues. Replacing the shaft with a genuine OEM part restores the mechanical integrity the X390 was built to deliver.
