The Multiquip 50011200 Key 6X6X25 2G40 Hatz is a genuine OEM component designed for RAMMAX walk-behind rollers including the RW1404, RW1404MR, and RW1504HF. As a direct OEM replacement, this key is manufactured to the exact tolerances required by Multiquip, ensuring proper torque transfer and component alignment in the drivetrain. Verify your serial number against fitment notes for the RW1404MR (S/N 326075 and up) and RW1504HF (up to S/N ) before ordering to confirm compatibility.
Key Features
- Genuine OEM Torque Specification — Manufactured to the exact dimensional profile (6x6x25mm) required for correct load-bearing engagement on Hatz-powered RAMMAX roller driveshafts.
- Direct Drop-In Replacement — Matches the original keyway geometry of the RW1404, RW1404MR, and RW1504HF, seating flush without filing or shimming.
- Serial Number Fitment Verified — Confirmed for RW1404MR S/N 326075 and up and RW1504HF up to S/N 1534188; always cross-reference your machine's serial plate before ordering.
- Prevents Shaft and Hub Damage — A worn or undersized key allows slippage between the shaft and mating component, which causes accelerated wear on both the keyway and hub bore — replacing it promptly protects surrounding drivetrain parts.
- Sourced from Multiquip's OEM Supply Chain — Sold by DHS Equipment as an authorized Multiquip part, carrying the same part number (50011200) used in Multiquip's official parts documentation.
A drive key is a small but critical fastening element fitted into a machined slot — called a keyway — cut into both a shaft and the hub of a mating component such as a sprocket, pulley, or gear. Its job is to lock the two parts rotationally so they turn together as a single unit, transferring power without slipping. When a key shears, deforms, or wears down, the hub can spin freely on the shaft, resulting in a complete loss of drive or erratic machine movement — and leaving the shaft and hub keyways exposed to rapid erosion that can make the next repair significantly more costly.
