The Wacker Neuson Annular Spring is a genuine OEM component designed for a wide range of Wacker Neuson tandem vibratory rollers, including the RD24, RD27, RD28, RD40, RD45, and RC70 series machines. Sourced directly from Wacker Neuson, this annular spring meets the same specifications as the part that left the factory, ensuring a consistent, dependable installation every time. Part number covers an extensive fitment range spanning standard, open-ROPS, cab, DPF, and electric variants across the RD and RC series. If your roller is down and you need a verified replacement, this is the correct part to order.
Key Features
- OEM Vibration Isolation Quality — Engineered to deliver the correct elasticity and load-bearing capacity for the drum isolation system, maintaining consistent vibration transfer to the ground without over-stressing surrounding components.
- Direct-Fit Replacement — Matches the original mount geometry and durometer of the factory annular spring, allowing straightforward installation without modification to the drum assembly.
- Broad Series Compatibility — Fits RD24, RD27, RD28, RD40, RD45, and RC70 series rollers, including standard, DPF-equipped, open-ROPS, cab, and electric variants — one part number covers the full lineup.
- Sustained Compaction Performance — A correctly functioning annular spring transmits drum vibration efficiently to the compaction surface; a cracked or hardened spring degrades amplitude output and leaves inconsistent compaction results.
- Genuine Wacker Neuson OEM Part — Supplied as an authentic Wacker Neuson replacement, carrying the part number 5100048638 exactly as listed in the original equipment documentation.
An annular spring is a rubber-bonded ring that sits between the vibrating drum and the roller's main frame, isolating machine-generated vibration so it is directed into the ground rather than transmitted through the chassis and operator station. It plays a central role in keeping the drum's eccentric vibration system functioning at the correct amplitude and frequency. When an annular spring cracks, hardens with age, or deforms under load, the drum can lose effective contact with the compaction surface, resulting in uneven density, increased machine stress, and potential damage to adjacent drum bearings and seals.
