The Wacker Neuson Upper Flange W/Bearing is a genuine OEM component designed for the RD27-100 and RD27-120 ride-on tandem roller series. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component installed at the factory. The is confirmed compatible across multiple configurations of the RD27 family, including RD27 Pro, RD27 Basic, and T4F-compliant variants.

Key Features
- Genuine OEM Bearing Integration — The bearing is pre-installed within the flange assembly, ensuring the rolling element is correctly seated and pre-aligned to OEM tolerancing from the moment of installation.
- Direct Bolt-On Replacement — Engineered to the same dimensions and mounting pattern as the original, this upper flange drops into place on RD27-series drum assemblies without rework or machining.
- Broad RD27 Family Coverage — Compatible with RD27-100 and RD27-120 models across Pro, Basic, and T4F configurations, covering a wide production range of Wacker Neuson ride-on tandem rollers.
- Drum Rotation Integrity — A worn or failed upper flange bearing introduces play into the drum assembly, causing uneven compaction passes and accelerated wear on surrounding components; replacing it restores smooth, consistent drum rotation.
- Genuine Part Assurance — As a genuine Wacker Neuson OEM part, the 5200012642 is held to the same material and dimensional standards as the component it replaces, supporting the long-term structural integrity of the drum assembly.
The upper flange with bearing serves as a critical mounting and rotational support point for the vibratory drum on the RD27 tandem roller. It secures the drum in alignment while allowing it to spin freely during compaction passes, with the integrated bearing absorbing the radial and axial loads generated by drum rotation and vibration. When the bearing wears or the flange becomes damaged, operators may notice drum wobble, unusual noise from the drum end, or a drop in compaction consistency — all signs that the assembly needs prompt replacement to keep the machine performing correctly.
