Key Features
- OEM-Spec Clamping Surface — manufactured to Husqvarna's exact tolerances, ensuring the blade seats flush and is held firmly without wobble or runout during cutting passes.
- Direct Bolt-On Replacement — matches the original mounting interface on the spindle assembly, allowing the inner flange to drop straight into position without modification.
- Broad Wall Saw Compatibility — fits the WS440HF, WS400, WS482, and WS440 track-mounted wall saws, covering multiple models in the Husqvarna wall saw lineup.
- Restored Blade Stability — a correctly fitted inner flange keeps the diamond blade properly anchored, maintaining cut accuracy and preventing lateral blade movement through reinforced concrete and masonry.
- Safe Blade Retention — the inner flange is a critical part of the blade clamping system; using a genuine OEM component ensures the blade is retained securely, reducing the risk of slippage under load.
The inner flange is a core element of the blade mounting assembly on a wall saw. It clamps against the blade from the inner face, working in conjunction with the outer flange to grip and center the diamond blade on the drive spindle. A worn, cracked, or out-of-tolerance inner flange compromises blade stability — leading to inaccurate cuts, increased vibration, and potential blade slippage. Replacing a damaged inner flange with a genuine Husqvarna part restores proper clamping force and ensures the blade tracks correctly along the cutting line.
