As a direct OEM replacement, this hub assembly ensures the same fit and material specifications as the original part installed at the factory.

Key Features
- Genuine OEM Bearing Cup Integration — Bearing cups are precision-matched to the hub bore to maintain correct load distribution and minimize drum wobble during mixing cycles.
- 4-Lug Bolt Pattern — The four-lug configuration matches the original drum mounting interface exactly, allowing straightforward installation without modification to the drum or frame.
- Confirmed Mixer Compatibility — Fits WM120SH, WM120PH, EM120S Series, and EM120P Series — covering both Whiteman and Essick 120-class mixer platforms.
- Structural Drum Support — A sound hub assembly keeps the drum centered and turning smoothly; a worn or damaged hub causes uneven rotation, accelerated bearing wear, and poor mix consistency.
- Direct OEM Sourcing — Supplied under Multiquip part number 3504, matching the manufacturer's own parts documentation for confident identification and ordering.
The hub with bearing cups serves as the central mounting point that connects the mixer drum to the machine's drive system. The bearing cups seat the roller bearings that allow the drum to rotate freely and evenly under load — when the cups are worn, pitted, or improperly seated, the drum develops play that stresses the entire drive assembly and causes inconsistent mixing. Replacing this assembly with a genuine OEM unit restores correct bearing preload and drum alignment, protecting the drivetrain and ensuring your mortar or plaster mixer delivers a uniform mix.
