Key Features
- Exact Dimensional Spec — Machined to a true 5/16" square cross-section at 1-1/8" length, ensuring flush seating in the keyway without shimming or modification.
- Genuine OEM Construction — Sourced directly from Multiquip, this key meets the hardness and shear-strength requirements for the MQS-185 drive application.
- Confirmed MQS-185 Fitment — Engineered specifically for the MQS-185, eliminating the compatibility uncertainty that comes with generic hardware-store keys.
- Maintains Positive Drive Engagement — A correctly sized drive key transfers torque cleanly between shaft and hub; an undersized or worn key causes slippage, vibration, and accelerated wear on mating components.
- Direct Drop-In Replacement — Matches the original keyway geometry of the MQS-185 so the key seats fully and the retaining components align correctly on reinstallation.
A drive key is a small but critical fastening component that locks a rotating part — such as a pulley, sprocket, or coupling hub — to its shaft so both turn together as a single unit. It fits into matching slots (keyways) cut into both the shaft and the hub, preventing rotational slippage under load. When a key shears, deforms, or wears down, the driven component begins to slip or spin freely on the shaft, resulting in loss of power transmission, accelerated damage to the keyways themselves, and potential machine shutdown. Replacing a worn or damaged key promptly with the correct OEM part — properly dimensioned and made from the right material grade — restores full torque transfer and protects the surrounding shaft and hub from further damage.
