Key Features
- OEM-Spec Washer Construction — Manufactured to Husqvarna's exact thickness and hardness tolerances, ensuring consistent clamping force at the blade arbor without deformation under load.
- Exact Arbor Interface Fit — Engineered to match the arbor geometry of the Soff-Cut150 series, seating flush against the blade flange for secure, centered blade retention.
- Soff-Cut150 Series Compatibility — Confirmed fitment for the Soff-Cut150, Soff-Cut150D, and Soff-Cut150E early entry concrete saws — one part number covering the full 150-class lineup.
- Blade Security Under Operating Stress — A correctly seated arbor washer maintains uniform pressure on the blade collar, preventing blade wobble and ensuring clean, accurate early-entry cuts in green concrete.
- Genuine Husqvarna OEM Part — Supplied as a genuine replacement, not an approximation, so it integrates into the blade assembly exactly as the original component did at the factory.
The arbor washer sits between the blade flange and the retaining nut on the cutter's spindle, distributing clamping load evenly across the blade collar to hold the diamond blade securely in place during operation. Without proper clamping, a blade can shift laterally or run off-center, leading to inaccurate cuts, accelerated blade wear, and potential safety hazards. A worn or damaged washer that no longer seats flat should be replaced promptly to restore correct blade retention and cutting performance.
