The Husqvarna 531119305 Key 5x5x14 is a genuine OEM replacement component designed for the FS700E floor saw. This drive key is sourced directly from Husqvarna, ensuring an exact dimensional match to the original part and a secure, rattle-free fit within the keyway. DHS Equipment supplies this part to help keep your floor saw operating at full capacity.
Key Features
- OEM-Matched Dimensions — Manufactured to Husqvarna's exact 5x5x14 profile, ensuring the key seats fully and correctly within the mating keyway without slop or stress concentration.
- Direct Drop-In Replacement — Installs directly into the FS700E keyway slot with no filing, shimming, or fitting required, restoring the original mechanical connection.
- FS700E Floor Saw Fitment — Confirmed genuine OEM fit for the FS700E walk-behind floor saw; cross-reference part number 531119305 against your parts diagram before ordering.
- Secure Power Transfer — A correctly fitted drive key locks the shaft and hub together, transmitting rotational force cleanly and preventing slippage that would otherwise damage the shaft or hub bore.
- Genuine Husqvarna Quality — Produced to the same material grade and hardness specification as the original, resisting shear and deformation under the high-torque demands of concrete cutting operations.
A drive key is a small precision component that sits in a machined slot — the keyway — between a rotating shaft and a hub or pulley, locking the two together so they turn as a single unit. Without a correctly fitted key, the shaft and hub can rotate independently, causing power loss, rapid wear to the keyway, and potential seizure or component failure. On a floor saw like the FS700E, where the drivetrain must handle sustained torque during concrete cutting, a worn or sheared key can lead to sudden loss of blade drive and costly secondary damage to the shaft or hub.
