The Multiquip 451423180 Drive Key R400G is a genuine OEM component designed for the R-400G static roller. As an authorized Multiquip OEM part, the part is manufactured to the exact specifications required for proper drive train engagement on R-400G equipment. Sourced directly through Multiquip's parts network, this is the correct replacement when the original drive key shows wear, shearing, or loss of torque transfer.
Key Features
- Genuine OEM Specification — Manufactured to the exact material hardness and dimensional tolerances required for drive key function in the R-400G roller drivetrain.
- Direct Drop-In Replacement — Matches the original keyway profile and seating dimensions of the R-400G, ensuring correct installation without machining or shimming.
- R-400G Static Roller Fitment — Confirmed fitment for the Multiquip R-400G static roller series.
- Torque Transfer Integrity — A correctly seated drive key locks the rotating component to the shaft, maintaining full power delivery; a worn or sheared key causes slippage, loss of drive, and accelerated shaft damage.
A drive key is a small but load-bearing component that sits in a machined slot between a shaft and a rotating part — such as a sprocket, pulley, or drum hub — to prevent the two from spinning independently of each other. It transmits torque from the shaft to the driven component, keeping the drivetrain locked together under operating loads. When a drive key shears or wears down, the shaft spins freely inside the hub, causing a complete loss of drive and often scoring the keyway itself, which can lead to more costly shaft or hub replacement if not addressed promptly.
