The Multiquip 50024 Square Key 1/4 x 35 mm is a genuine OEM component designed for Multiquip concrete mixer and roller equipment, including MC94P/S, MC44S, MC94SK, MC94PK, MC12PH, and RW1810 models. As a direct OEM replacement, this key is manufactured to exact dimensional tolerances to ensure a proper fit in the keyway with no slop or misalignment. Sourced directly through authorized Multiquip channels, the 50024 is the correct part to specify when servicing the drive train or drum assembly on compatible equipment.
Key Features
- Exact OEM Dimensions — Manufactured to the precise 1/4 x 35 mm profile required by the original keyway, ensuring flush seating and full torque transfer without rocking or shifting.
- Genuine Multiquip Part — Sourced directly from Multiquip, this square key meets the same material grade and hardness specifications as the original component it replaces.
- Broad Mixer and Roller Fitment — Confirmed compatible with MC94P/S, MC44S, MC94SK, MC94PK, MC12PH, and RW1810 equipment, covering several concrete mixer and roller configurations in the Multiquip lineup.
- Drive Integrity Protection — A correctly sized and seated square key locks the shaft and hub together under load; a worn or damaged key allows slippage that accelerates wear on both the shaft and the mating component.
- Simple Drop-In Service Part — Small profile and standard square geometry make installation straightforward during routine drivetrain or drum maintenance intervals.
A square key is a small but critical drivetrain component that sits in a machined slot — called a keyway — between a rotating shaft and a hub, sprocket, or drum. Its job is to lock those two parts together so they rotate as a single unit, transferring torque from the engine or motor to the working component without slippage. When a square key wears down, shears, or falls out, the shaft spins freely inside the hub, causing the connected drum or drive component to stop turning entirely — which halts operation until the key is replaced.
