The Wacker Neuson Machined Hub is a genuine OEM component designed for the RD12A-90, RD12-90, RD11V, and RD11A tandem roller series. Sourced directly from Wacker Neuson, this hub is precision-machined to the exact tolerances required for proper drum mounting and alignment on these walk-behind and ride-on double-drum rollers. Its direct OEM lineage means the installs to the same specifications as the original part, with no guesswork on fitment across the compatible RD-series models. If your roller drum is showing signs of wear, vibration irregularities, or hub damage, replacing it with the correct machined hub is essential to restoring proper compaction performance.
Key Features
- OEM Precision Machining — Turned and finished to exact dimensional tolerances, ensuring consistent drum concentricity and smooth rotation under load on double-drum roller applications.
- Direct Drum Interface Fit — Engineered to bolt directly into the drum assembly of compatible RD-series rollers, aligning with existing mounting points without rework or shimming.
- Broad RD-Series Compatibility — Confirmed fitment across RD12A-90 (including foldable ROPS variants), RD12-90, RD11V, and RD11A tandem rollers.
- Maintains Drum Stability Under Vibration — A worn or damaged hub introduces drum wobble and uneven compaction passes; a properly seated machined hub keeps drum rotation true during vibratory operation.
- Genuine Wacker Neuson OEM Part — Carries the full backing of Wacker Neuson's parts supply chain, ensuring material grade and finish match the original production specification.
The drum hub is the central mounting interface between the roller's drum shell and its drive or bearing shaft. It transfers rotational force evenly across the drum while supporting the structural load of the machine during compaction passes. When a hub wears, cracks, or develops dimensional distortion, the drum loses concentricity — resulting in uneven contact with the compaction surface, increased vibration transmitted to the frame, and accelerated wear on surrounding bearings and seals. Replacing a damaged hub with a correctly machined OEM unit restores proper drum geometry and protects the integrity of the surrounding drivetrain components.
