The Wacker Neuson Spacer Ring is a genuine OEM component designed for the RD24-100, RD27-120, RD40-130, and RD45-140 series tandem rollers. Sourced directly from Wacker Neuson, this part meets the exact tolerances and material specifications of the original, ensuring a correct drop-in fit within the drum or drive assembly it services. Fitment spans a broad range of RD-series configurations including standard, C, O, and US variants across multiple production generations, making the one of the most widely applicable spacer components in the RD tandem roller lineup.
Key Features
- OEM Dimensional Accuracy — Manufactured to Wacker Neuson's original tolerances, ensuring the correct axial spacing and load distribution specific to tandem roller drum and drive assemblies.
- Direct Drop-In Installation — Matches the original mounting position and profile, allowing straightforward installation without rework or shimming.
- Broad RD-Series Compatibility — Fits RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 tandem rollers across standard, C (cab), O (open), US, and .3-generation variants.
- Maintains Proper Component Alignment — A correctly fitted spacer ring keeps rotating or clamped components correctly positioned; a worn or missing spacer can cause uneven wear, vibration, and premature bearing or shaft damage.
- Genuine Wacker Neuson Part — Supplied as an authorized OEM replacement, confirming material grade and geometry match the part originally installed at the factory.
A spacer ring is a precision-machined component used to set and maintain the correct gap or positional offset between two adjoining parts — typically within a drum shaft, bearing housing, or drive assembly. On tandem rollers like the RD-series, maintaining accurate spacing between rotating components is critical to even load transfer, smooth drum operation, and the longevity of surrounding bearings and seals. When a spacer ring wears down or is damaged, it can allow components to shift axially, leading to vibration, accelerated wear on adjacent parts, and potential drivetrain or compaction performance issues.
