The Wacker Neuson 5100012226 is a genuine OEM Cylindrical Roller Bearing designed for the RD-series tandem rollers, covering a wide range of RD24, RD27, RD28, RD40, and RD45 configurations including standard, combination-drum, DPF-equipped, and electric-hybrid variants. Sourced directly from Wacker Neuson, part number 5100012226 meets the exact tolerancing and load ratings specified for these machines at the factory. This bearing supports critical rotating assemblies within the roller drivetrain, making it an essential component for keeping compaction performance at full capacity. Confirmed fitment spans an extensive range of walk-behind and ride-on articulated tandem roller models used in asphalt and soil compaction applications.
Key Features
- OEM-Spec Load Tolerancing — Manufactured to the exact radial load capacity and dimensional tolerances specified for the RD-series drivetrain, ensuring the bearing seats and performs as designed.
- Drop-In Replacement — Matches the original bearing's bore, outer diameter, and width, allowing straightforward installation without machining or shimming.
- Broad RD-Series Fitment — Compatible with RD24, RD27, RD28, RD40, and RD45 tandem rollers across standard, open-drum (O), combination (C), DPF, and electric-hybrid (e) variants.
- Sustained Compaction Output — A correctly fitted cylindrical roller bearing maintains smooth drum rotation under vibratory load; a worn bearing causes vibration imbalance, uneven compaction, and accelerated drivetrain wear.
- Genuine Wacker Neuson Part — Supplied as genuine OEM, confirming the part number, material grade, and heat treatment are identical to the component installed at the factory.
A cylindrical roller bearing is a precision-engineered component that supports rotating shafts by carrying radial loads with minimal friction through a set of cylindrical rolling elements held in a precision cage. In a tandem roller like the RD24 through RD45 series, these bearings support the drum drive and vibratory shaft assemblies, allowing them to spin freely under the high dynamic loads generated during compaction passes. When a cylindrical roller bearing begins to wear, the symptoms include abnormal noise from the drum assembly, increased vibration at the operator platform, and ultimately drivetrain damage if the bearing is allowed to fail completely — making timely replacement with the correct OEM part critical to machine longevity.
