Key Features
- Genuine OEM Construction — Manufactured to original Multiquip tolerances, delivering the precise torque transfer and dimensional accuracy that a coupling and hub assembly demands.
- Direct Drop-In Replacement — Engineered to mount and connect exactly as the original, aligning with existing shaft and hub interfaces on the MRX-440P without additional machining or adaptation.
- Confirmed MRX-440P Fitment — Verified for the Multiquip MRX-440P walk-behind roller, so you can order with confidence knowing this is the correct assembly for your machine.
- Drive System Integrity — A worn or damaged coupling can cause erratic power delivery, vibration, and loss of drive engagement; replacing it promptly with this part restores smooth, consistent operation.
- Complete Hub Assembly — Supplied as a coupling with hub, meaning the critical mating components come together as a matched unit for proper load distribution and longevity.
A coupling with hub serves as the mechanical link between a drive shaft and a driven component, transmitting rotational force while absorbing minor misalignment and shock loads. On a walk-behind roller like the MRX-440P, this assembly is critical to maintaining consistent drum drive and overall machine control. When the coupling wears or fails, operators may notice vibration, slipping drive engagement, or complete loss of power to the drum — all of which halt productive compaction work and warrant immediate replacement.
