The Wacker Neuson is a genuine OEM 12.0 X 8 X 70 Key designed for the BFS 2575KLS floor saw and the DFS 2075HLS diesel walk-behind saw. As a direct OEM part sourced from Wacker Neuson, the is manufactured to the exact dimensions and material tolerances required for correct power transfer and shaft engagement in these saws. Choosing a genuine OEM component means you get the exact fit your machine was built around, with no uncertainty about dimensional accuracy or material compatibility. This key is an essential drivetrain component that keeps cutting performance consistent and protects against slippage under load.
Key Features
- Exact Dimensional Spec: — Machined to 12.0 x 8 x 70 mm, matching the precise keyway geometry required for secure shaft-to-hub engagement in Wacker Neuson floor and walk-behind saws.
- Genuine OEM Part: — Sourced directly from Wacker Neuson, ensuring the correct material hardness and shear strength for sustained cutting loads.
- Direct-Fit Compatibility: — Confirmed fitment for the BFS 2575KLS floor saw and DFS 2075HLS diesel walk-behind saw; drops into the existing keyway without rework.
- Drivetrain Integrity: — A properly seated key prevents rotational slippage between the shaft and driven component, maintaining blade speed consistency and protecting adjoining shaft surfaces from wear damage.
- Verified Part Number: — Order with confidence using OEM part number 5000128220 to ensure you receive the correct key for your application.
A woodruff or parallel key like the 5000128220 is a small but critical drivetrain component that locks a rotating shaft to a hub, pulley, or gear, transmitting torque between them without slippage. In a floor saw or walk-behind saw, this key sits in a precisely cut slot between the engine or gearbox shaft and a driven component, keeping everything turning in unison under the high loads of concrete or asphalt cutting. When a key shears or wears, the shaft spins independently of the driven component, resulting in immediate loss of blade drive and potential damage to the surrounding keyway surfaces.
