Wacker Neuson 5000112391 Du Bearing 20 X 20

The Wacker Neuson is a genuine OEM Du Bearing 20 X 20 designed for the RD7 series walk-behind tandem rollers, including the RD7H-ES, RD7H-S, and RD7 double drum vibratory roller variants. As a direct Wacker Neuson OEM component, the is manufactured to the same tolerances as the original bearing installed at the factory, ensuring proper load distribution and consistent rotational performance within the drum or drive assembly. This bearing is confirmed to fit across multiple RD7 configurations, making it a reliable choice whether you are servicing an EU-spec or standard domestic machine. Keep a spare on hand to support planned maintenance intervals and avoid unscheduled stops during compaction operations.

Key Features

• OEM-Grade Bearing Tolerancing — Manufactured to the exact dimensional spec of 20 x 20, ensuring the correct radial and axial load capacity for this roller application without compromise.
• Drop-In Installation — Matches the original bearing seat geometry in the RD7 drum and drive assemblies, so the part seats and retains correctly without machining or shimming.
• Broad RD7 Series Fitment — Confirmed compatible with the RD7H-ES, RD7H-S (including EU variants), and RD7 double drum vibratory roller platforms across multiple machine numbers.
• Sustained Drum Performance — A correctly specified bearing keeps the drum spinning true and transfer of compaction force consistent; a worn or undersized bearing causes vibration irregularity, drum wobble, and accelerated wear on adjacent components.
• Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5000112391 carries the full OEM designation, supporting equipment serviceability and parts traceability.

A Du bearing is a self-lubricating plain bearing constructed from a composite material — typically a steel backing bonded with a porous bronze layer and a PTFE-based surface liner. In a walk-behind tandem roller like the RD7 series, bearings of this type are commonly used in pivot points, drum shaft assemblies, and articulation joints where continuous low-friction movement is required under significant compressive load. When this bearing wears through its liner, metal-on-metal contact begins, causing heat buildup, increased play in the joint, and eventual damage to the mating shaft or housing — making timely replacement essential to keeping the roller operating correctly.
