The Wacker Neuson is a genuine OEM Square Key 3/16 X 3/16 X 1-1/8 designed for the BFS 2020AS and BFS 1318AS walk-behind floor saws. Sourced directly from Wacker Neuson, this part matches the exact dimensions and material grade specified for these machines, ensuring proper torque transfer between the shaft and driven component. Correct sizing is critical on floor saw driveline components, and the delivers the precise fit the manufacturer intended. If your saw is showing signs of blade shaft slippage or play in the drive assembly, this key is the correct OEM replacement to restore proper operation.
Key Features
- OEM-Specified Dimensions: — Cut to the exact 3/16 x 3/16 x 1-1/8 specification, ensuring full contact across the keyway for maximum torque transfer without deformation.
- Direct Drop-In Replacement: — Slots directly into the existing keyway on BFS 2020AS and BFS 1318AS floor saws with no modification to the shaft or hub required.
- Confirmed BFS Floor Saw Fitment: — Verified for the BFS 2020AS and BFS 1318AS self-propelled walk-behind concrete saws, covering both models in the BFS series.
- Maintains Drive Integrity: — A worn or undersized key allows the blade shaft or pulley to slip under load, causing irregular cuts and accelerated wear on surrounding components — this genuine part restores the positive lock the drivetrain depends on.
- Genuine Wacker Neuson OEM Part: — Manufactured to Wacker Neuson's material and hardness standards, so the key shears predictably under overload rather than damaging the shaft or hub.
A square key is a small but load-bearing component that locks a rotating shaft to a gear, pulley, or sprocket, transmitting torque without allowing the two parts to spin independently. In a walk-behind floor saw like the BFS series, the key secures drive components along the blade shaft or belt drive system, keeping power delivery consistent through demanding concrete cutting cycles. When the key wears, shears, or goes missing, the shaft and hub rotate independently, causing loss of drive, erratic blade behavior, and potential damage to the keyway itself if left uncorrected.
