The Wacker Neuson Supporting Disc is a genuine OEM component designed for the BFS 80, BFS 100, and DFS 90 gasoline and diesel floor saw series. As a direct factory replacement, this supporting disc installs to OEM specification, ensuring the blade assembly seats and spins exactly as designed. Wacker Neuson genuine parts are manufactured to the same standards as the original components, so you can trust the to perform exactly as the machine requires. Confirmed fitment spans the BFS 80, BFS 100, and DFS 90 models — always cross-reference your machine's serial number before ordering.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to exact Wacker Neuson tolerances, ensuring the disc seats flush against the blade flange without wobble or misalignment.
- Direct Bolt-On Replacement — Matches the original mounting configuration on BFS and DFS series saws, so the disc drops into place without modification to the arbor or blade guard hardware.
- Confirmed Fitment Across Three Models — Compatible with the BFS 80 (Ø 350), BFS 100 (Ø 450/350), and DFS 90 floor saws, covering both gasoline and diesel variants in the range.
- Blade Stability Under Load — A correctly functioning supporting disc keeps the cutting blade centered and stable during deep slab cuts; a worn or cracked disc can cause blade flutter, uneven cuts, and accelerated wear on the spindle.
- Blade Retention Safety — The supporting disc is part of the blade clamping system; using a genuine OEM disc maintains the clamping force and geometry needed to securely retain the blade at operating speed.
The supporting disc forms part of the blade mounting assembly on a floor saw, sandwiching the diamond or abrasive cutting blade between the inner and outer flanges on the drive spindle. It distributes clamping force evenly across the blade collar, keeping the blade true and preventing lateral movement during cutting. When a supporting disc becomes cracked, warped, or worn, blade runout increases — leading to rough, wandering cuts and putting additional stress on the spindle bearings.
