The Wacker Neuson Pendulum Suspension is a genuine OEM component designed for the RD24-100, RD27-120, and RD28-120 tandem roller series, including standard, C, O, DPF, and electric variants. Sourced directly from Wacker Neuson, this part carries the same specifications as the original installed at the factory, ensuring a correct, matched replacement every time. It covers an extensive range of RD-series tandem rollers across multiple build generations, making it the dependable choice for fleet operators and service technicians working across mixed machine lineups. Confirm your model and serial number against the fitment list before ordering to ensure compatibility with your specific machine.
Key Features
- Genuine OEM Articulation Geometry: — Manufactured to Wacker Neuson's original pivot and suspension tolerances, preserving the steering response and drum alignment the machine was engineered to deliver.
- Direct-Mount Replacement: — Matches the original mounting points and hardware interface on RD-series tandem rollers, so the part seats correctly without reworking the frame connection.
- Broad RD-Series Coverage: — Fits RD24-100, RD27-120, and RD28-120 models across standard, C, O, DPF, and electric configurations, spanning multiple production generations.
- Smooth Articulation Under Load: — A correctly functioning pendulum suspension allows the roller drums to follow uneven ground independently, maintaining consistent compaction contact across the full drum width.
- Structural Compliance for Safe Operation: — The pendulum suspension is a load-bearing articulation point; using a genuine OEM part maintains the structural integrity required for safe machine handling on slopes and uneven terrain.
The pendulum suspension connects the front and rear drum frames of a tandem roller, allowing them to pivot and tilt independently as the machine travels over uneven ground. This articulation keeps both drums in firm, even contact with the compaction surface regardless of minor grade changes, which is critical for achieving uniform density across a pass. When the pendulum suspension wears or fails, the drums can lose ground contact on one side, producing inconsistent compaction, increased vibration transferred to the frame, and potential handling instability — all of which affect both output quality and operator safety.
