The Husqvarna 541206885 Key 1/4 Square x 1-1/8 Inch Long Round One End is a genuine OEM component designed for the RS8500D floor saw. As a factory-original part, it is manufactured to Husqvarna's exact dimensional tolerances, ensuring correct engagement within the drivetrain assembly. DHS Equipment supplies this part to help keep your RS8500D floor saw operating at full capacity.
Key Features
- OEM Dimensional Accuracy — Manufactured to Husqvarna's exact 1/4-inch square profile and 1-1/8-inch length specification, ensuring proper keyway engagement and torque transfer without slop or misalignment.
- Direct Drop-In Replacement — Matches the original key geometry exactly, including the rounded end profile, so it seats correctly in the shaft and hub keyways without modification.
- Built for the RS8500D Floor Saw — Verified fitment for the RS8500D floor saw, cross-reference part number 541206885 against your machine's parts diagram before ordering.
- Restored Drive Integrity — A correctly fitted drive key locks rotating components securely to the shaft, preventing slippage that would otherwise cause erratic blade speed, premature wear, or loss of cutting performance.
- Genuine Husqvarna OEM Quality — Sourced directly from Husqvarna's authorized parts network, this component meets the same material and hardness standards as the part installed at the factory.
A drive key is a small but critical component that sits in a machined slot — called a keyway — between a rotating shaft and a hub or gear, locking the two together so torque is transmitted evenly without slippage. On a floor saw like the RS8500D, maintaining a secure keyed connection is essential for consistent blade drive and accurate cutting performance. When a key shears, wears, or is missing entirely, the connected component can spin freely on the shaft, resulting in lost drive, vibration, and potential damage to surrounding components.
