The Wacker Neuson Unbalance is a genuine OEM component designed for the RD24-100, RD27-120, and RD28-120 series tandem rollers. Sourced directly from Wacker Neuson, this part meets the exact engineering standards set for these machines, so there is no guesswork about calibration or fitment when you install it. It is confirmed compatible across multiple variants of the RD24-100 and RD28-120 series, including DPF-equipped and updated generation models.
Key Features
- OEM-Calibrated Vibration Mass — Manufactured to the exact eccentric weight specification required to produce correct centrifugal force output in the drum assembly.
- Drop-In Drum Fitment — Engineered to match the original mounting geometry inside the vibratory drum, so installation aligns directly with existing shaft and housing interfaces.
- Broad Series Compatibility — Fits multiple variants across the RD24-100, RD27-120, and RD28-120 tandem roller families, including standard, US-spec, Generation 3, and DPF-equipped models.
- Consistent Compaction Output — A correctly functioning unbalance delivers stable, repeatable amplitude and frequency, keeping compaction performance on spec across the full working range of the roller.
- Genuine Wacker Neuson Part — Supplied as an authorized OEM replacement, ensuring the part number, material grade, and balancing match what left the factory originally.
The unbalance — sometimes called an eccentric weight or vibration mass — is the rotating component inside a roller's vibratory drum that generates the compaction force. As it spins, its off-center mass creates centrifugal force that drives the drum into a rapid up-and-down vibration pattern, allowing the roller to compact soil, gravel, or asphalt far more effectively than static weight alone could achieve. When the unbalance is worn, damaged, or out of specification, amplitude drops, compaction becomes uneven, and the machine may begin to produce excessive or irregular vibration that puts stress on bearings and other drum components.
