The Husqvarna 541202488 Key 3/8 Square X 3 1/2 is a genuine OEM replacement component designed for the Pro65G floor saw. As a genuine Husqvarna part, it is manufactured to the same specifications as the original, ensuring correct fitment and consistent drive engagement on the Pro65G. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- OEM-Spec Dimensional Accuracy — Manufactured to Husqvarna's exact 3/8 square profile and length tolerances, ensuring the key seats correctly in its keyway without play or slop.
- Drop-In Replacement — Matches the original component profile exactly, sliding directly into the shaft and hub keyway of the Pro65G without any rework or modification to the mating parts.
- Pro65G Floor Saw Compatibility — Verified fitment for the Pro65G floor saw, so you can cross-reference part number 541202488 against your parts diagram with confidence.
- Torque Transfer Integrity — A correctly fitted drive key locks the shaft and hub together so power is transmitted cleanly; a worn or missing key causes the hub to slip, leading to lost cutting performance and potential damage to the shaft or blade arbor.
- Genuine Husqvarna Quality — Sourced directly through Husqvarna's OEM supply chain, this key is made from appropriate hardened stock to resist shear and deformation under the rotational loads typical of floor saw operation.
A drive key is a small but structurally critical component that fits into machined slots — keyways — on both a rotating shaft and its mating hub or pulley. It creates a positive mechanical lock between the two parts, preventing relative rotation and ensuring that torque is transferred efficiently from the shaft to the driven component. When a key shears, deforms, or goes missing, the shaft and hub spin independently, causing loss of drive, accelerated wear to the keyway surfaces, and potential damage to surrounding components that can be far more costly to repair.
