As a direct OEM replacement, this shaft key is manufactured to the exact dimensional tolerances required by the original equipment, ensuring a proper fit between the shaft and mating component. Verified fitment includes the WM63E, WM63H5, WM63H8, WM63SLF, MQ600H, MQ600HTB, and MQ600HTP. Sourced through DHS Equipment as an authorized Multiquip parts distributor, you can order with confidence knowing this is the correct part for your machine.
Key Features
- Genuine OEM Steel Construction — Manufactured from steel to the original dimensional spec, delivering the shear strength and hardness required for continuous power transmission under load.
- Drop-In Shaft Fit — Sized at 3/8" square by 2.00 inches to seat directly into the existing keyway without modification, restoring the positive shaft-to-hub connection immediately.
- Broad Fitment Coverage — Compatible with WM63E, WM63H5, WM63H8, and WM63SLF Whiteman mixers, as well as MQ600H, MQ600HTB, and MQ600HTP trash pumps.
- Torque Transfer Integrity — A correctly fitted shaft key locks the rotating component to the shaft, preventing slippage that causes premature wear on both the shaft and hub bore.
- Drive Safety Under Load — In pump and mixer applications, a worn or missing key allows the driven component to spin freely on the shaft, resulting in loss of drive and potential damage to surrounding components.
A shaft key is a small but critical fastening component that locks a rotating part — such as a pulley, sprocket, or impeller — to a drive shaft, ensuring both rotate together as a single unit. It sits in a machined slot called a keyway, cut into both the shaft and the hub of the driven component, and transmits torque between them without relying solely on friction or fasteners. When a shaft key shears, deforms, or goes missing, the driven component loses its positive connection to the shaft, causing slippage, loss of output, and accelerated wear on the keyway surfaces that can eventually require shaft replacement.
