The Wacker Neuson Supporting Disc is a genuine OEM component designed for the BFS series gasoline floor saws, including the BFS 935A, BFS 1345A, BFS 1345AS, BFS 1350A, BFS 1350AS, and related AL and ALS variants. As a direct factory replacement, this part ships with the exact specifications required to restore the blade drive system to proper working order. Sourcing the correct supporting disc by part number ensures the blade assembly seats and runs true — critical for straight, accurate cuts in concrete and asphalt.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's original tolerances, ensuring the disc interfaces correctly with the blade flange and drive arbor without rework or shimming.
- Direct Drop-In Replacement — Engineered to mount in the same position as the original, the 5000124120 installs using existing hardware and fastener patterns on BFS series floor saws.
- Broad BFS Series Compatibility — Fits BFS 935A, BFS 935AL, BFS 1335A, BFS 1345A, BFS 1345AL, BFS 1345AS, BFS 1345ALS, BFS 1350A, BFS 1350AL, BFS 1350AS, BFS 1350ALS, BFS 1350L, and BFS 1345K models.
- Blade Stability Under Load — A correctly functioning supporting disc keeps the cutting blade firmly clamped and centered, delivering smooth, controlled cuts through reinforced concrete slabs and asphalt surfaces.
- Blade Retention Safety — The supporting disc is a primary blade-clamping component; using a worn or out-of-spec disc risks blade slippage during operation, making this a safety-critical replacement on any floor saw.
The supporting disc on a floor saw acts as the inner clamping face that holds the diamond or abrasive cutting blade securely against the drive flange on the blade arbor. It distributes clamping force evenly across the blade collar, preventing lateral movement or wobble during cutting. When the supporting disc becomes worn, cracked, or dimensionally distorted, blade runout increases — leading to uneven cuts, accelerated blade wear, and the risk of blade loosening under the high rotational forces generated during concrete or asphalt sawing.
