The Wacker Neuson Inner Flange is a genuine OEM component designed for the BFS 2020AS and BFS 1318AS self-propelled walk-behind floor saws. As a direct factory replacement, the is manufactured to the exact dimensions required for correct blade retention and concentricity on these machines. Sourcing a genuine Wacker Neuson Inner Flange ensures the blade clamping assembly functions exactly as the machine was engineered to operate, maintaining cutting accuracy and operator confidence on slab and flatwork applications.
Key Features
- Genuine OEM Dimensional Accuracy — Machined to the exact bore diameter and mating surface profile required for proper blade seating on BFS-series floor saws, ensuring zero blade runout from the flange itself.
- Direct Replacement for BFS Floor Saws — Engineered to drop into the blade arbor assembly of the BFS 2020AS and BFS 1318AS without additional fitting or machining.
- Confirmed Fitment — Verified for the BFS 2020AS walk-behind saw and the BFS 1318AS self-propelled walk-behind saw platforms.
- Blade Stability Under Load — A correctly seated inner flange maintains consistent clamping force against the blade, preventing vibration, wandering cuts, and premature blade wear during heavy concrete or asphalt cutting passes.
- Safety-Critical Blade Retention — The inner flange is part of the blade clamping system; a worn or damaged flange can allow blade movement during operation, making replacement with a correctly spec'd OEM part essential for safe machine use.
The inner flange is one half of the blade clamping pair that secures the diamond or abrasive cutting blade to the arbor shaft of a floor saw. Working together with the outer flange and arbor nut, it clamps the blade firmly in place and transfers rotational force from the drive system evenly across the blade hub. When an inner flange is worn, cracked, or dimensionally out of spec, the blade can shift under the clamping load, causing vibration, inaccurate cuts, and potentially unsafe blade release — making timely replacement a critical part of floor saw maintenance.
