The Husqvarna 581557301 Flange Washer is a genuine OEM component designed for the MS360 masonry saw. Sourced directly from Husqvarna, this flange washer delivers an exact fit to the original specification, ensuring proper blade clamping and secure mounting at the arbor. DHS Equipment supplies this part to help keep your MS360 running at full capability.
Key Features
- OEM Clamping Surface Integrity — Manufactured to Husqvarna's dimensional tolerances, this flange washer maintains the correct contact surface area and load distribution at the blade arbor — critical for consistent clamping force.
- Direct Arbor Replacement — Engineered to match the original mounting interface of the MS360, this washer seats correctly against the flange without adjustment or reworking of the arbor assembly.
- MS360 Masonry Saw Fitment — Confirmed fit for the MS360, keeping your masonry saw operating with components built to the same specification as the original machine.
- Blade Security and Cut Accuracy — A properly seated flange washer holds the blade firmly and concentrically on the arbor. A worn or damaged washer can allow blade movement, leading to imprecise cuts and accelerated wear on surrounding components.
- Operational Safety at the Blade Arbor — Correct blade retention is a fundamental safety requirement on any masonry saw. Using a genuine OEM flange washer ensures the clamping assembly performs as the machine was engineered to operate.
The flange washer sits between the blade and the arbor flange, distributing clamping load evenly across the blade's mounting bore when the arbor nut is tightened. This even distribution is what keeps the blade running true and prevents lateral movement during cutting. When a flange washer becomes worn, deformed, or corroded, clamping force becomes uneven, which can cause blade wobble, rough cuts, and excessive stress on the spindle bearings. Replacing it with a correctly sized OEM part restores the geometry of the entire blade retention assembly.
