The Wacker Neuson Key 6 X 4 X 20 is a genuine OEM component designed for the BFS1214, MFS14, MFSX14, and BFS 614 series floor saws. As a direct Wacker Neuson OEM part, is manufactured to the exact dimensions and material grade required for proper installation and operation. This key fits across a broad range of Wacker Neuson floor saw configurations, including the BFSX1214 and MFSX14 RAW variants, making it a versatile stock item for service departments and contractors running mixed fleets. Verify your model number against the fitment list before ordering to ensure a correct match.
Key Features
- Exact Dimensional Accuracy — Machined to a precise 6 x 4 x 20 mm profile, ensuring correct engagement between shaft and hub with no slop or misalignment.
- Genuine OEM Part — Sourced directly from Wacker Neuson, this key meets the same material hardness and tolerance specifications as the original installed at the factory.
- Broad Floor Saw Compatibility — Confirmed fitment across BFS1214, MFS14, MFSX14, BFSX1214, and BFS 614 series floor saws, covering multiple build variants and serial number ranges.
- Positive Power Transfer — A correctly fitted key locks rotating components in proper phase alignment, preventing slippage that would cause blade speed loss, uneven cutting, or premature wear on mating parts.
- Simple Service Part — Drops into the existing keyway without modification, making it a straightforward replacement during scheduled maintenance or drivetrain repairs.
A key is a small precision fastener that sits in a machined slot — called a keyway — cut into both a shaft and the hub of a mating component such as a pulley, sprocket, or gear. It locks the two parts together rotationally so that torque is transferred from one to the other without slipping. On a floor saw, this type of key is critical to keeping the drive system synchronized; if the key shears or wears, the driven component can spin freely on the shaft, resulting in a loss of cutting power or complete drivetrain failure. Replacing a worn or damaged key promptly restores the positive mechanical connection and protects the surrounding shaft and hub surfaces from further damage.
