The Wacker Neuson Cup Spring is a genuine OEM component designed for the RC110 and RC110P series ride-on compactors, including US ROPS and US CAB configurations. As a factory-sourced part, it is manufactured to the same specifications as the original, ensuring a direct fit with no guesswork on compatibility. This cup spring is confirmed for use across the full RC110 and RC110P model lineup, covering both standard and enclosed cab variants sold in the US market. If you're servicing any of these machines, verifying the part number against your serial tag before ordering is always the best practice.
Key Features
- OEM Spring-Rate Accuracy — Sourced directly from Wacker Neuson, this cup spring meets the original load and deflection tolerances specified for the RC110 compactor platform.
- Drop-In Replacement — Matches the original mounting dimensions and stack orientation, so installation follows the standard service procedure without adaptation.
- Broad RC110 Series Coverage — Fits RC110, RC110P, RC110 US ROPS, RC110P US ROPS, RC110 US CAB, and RC110P US CAB models in a single part number.
- Sustained Clamping and Cushioning Performance — A worn or fatigued cup spring loses its preload, which can result in loosening, vibration transfer, or inconsistent mechanical engagement within the assembly it supports.
- Genuine OEM Assurance — Backed by Wacker Neuson as an authorized replacement, this part carries the same quality traceability as the component originally installed at the factory.
A cup spring — also called a Belleville washer or disc spring — is a conical, washer-shaped component that stores and applies axial load across a joint or assembly. It works by compressing under load to maintain consistent preload, absorb shock, and compensate for thermal expansion or mechanical settling in a bolted connection or drive system. When a cup spring wears out, becomes deformed, or loses its spring tension, the assembly it supports can develop play, vibration, or fastener loosening, which accelerates wear on surrounding components and reduces machine reliability over time.
