The Wacker Neuson 5100011980 is a genuine OEM Bearing Bush designed for the RD18-80, RD18-100, and RD18-100 C tandem roller series. As a direct OEM replacement, this part is produced to the same specifications as the original component installed at the factory, ensuring a correct, confident fit across all covered RD18 configurations. Verified fitment spans both standard and SE variants of the RD18-80 and RD18-100, including US-market models and the RD18-100 C combination roller. Keeping the correct Bearing Bush in service is essential for maintaining smooth drum and drivetrain operation on these walk-behind and articulated tandem rollers.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the original bore tolerance and material specification, ensuring correct load distribution and rotational clearance within the bearing housing.
- Direct Drop-In Replacement — Matches the original mounting dimensions of the RD18 series, allowing straightforward installation without secondary machining or shimming.
- Broad RD18 Series Fitment — Covers RD18-80, RD18-80 SE, RD18-100, RD18-100 SE, RD18-100 C, and corresponding US-market variants in a single part number.
- Supports Smooth Drum Operation — A correctly functioning Bearing Bush maintains proper shaft alignment and reduces friction at the pivot or drum shaft interface, preserving consistent compaction output across asphalt and soil applications.
- Protects Adjacent Components — A worn or failed Bearing Bush allows excess play at the shaft, which accelerates wear on surrounding housings, seals, and shafts — replacing it promptly limits the cost and scope of repairs.
A bearing bush is a plain bearing — a cylindrical sleeve pressed into a housing to support a rotating or oscillating shaft. On tandem rollers like the RD18 series, bearing bushes are used at pivot points and drum shaft locations to absorb radial loads while allowing controlled movement. When a bearing bush wears thin or seizes, it introduces shaft play that can produce vibration, uneven drum tracking, and accelerated damage to the surrounding assembly. Replacing a worn Bearing Bush with the correct OEM part restores the original shaft fit and keeps the roller performing at its designed compaction capacity.
