The Wacker Neuson 5100022919 Cup Spring is a genuine OEM component designed for the RC50, RC70, RC50p, RC70p, and RC70vo series single-drum soil compactors. As a direct OEM replacement, this cup spring is sourced to the exact specification used in original production, ensuring a straight-swap installation with no guesswork. It fits a wide range of RC-series configurations including standard, DPF ROPS, DPF CAB, and US-spec variants across both the RC50 and RC70 families. When spring components wear or lose tension, machine performance and component clamping integrity can be compromised — replacing with the correct OEM part gets your compactor back to spec.
Key Features
- Genuine OEM Spring Rate: — Manufactured to the original load and deflection specification, maintaining consistent clamping force that an aftermarket substitute may not replicate.
- Direct Drop-In Replacement: — Matches the original seating geometry and stack dimensions, fitting the existing assembly without modification to surrounding hardware.
- Broad RC-Series Coverage: — Compatible with RC50, RC50p, RC70, RC70p, and RC70vo models across standard, DPF ROPS, DPF CAB, and US-spec configurations.
- Sustained Clamping Integrity: — A correctly functioning cup spring maintains consistent preload on critical fastener assemblies; a fatigued spring can allow unwanted movement and accelerated wear of adjacent components.
- Verified Part Number: — Part number 5100022919 cross-references directly to the full RC50 and RC70 model lineup, giving you confidence you are ordering the right component for your machine.
A cup spring — also known as a Belleville washer or disc spring — is a conical, washer-shaped component that stores and applies a precise axial load when compressed. In heavy compaction equipment like the RC-series single-drum soil compactors, cup springs are used to maintain consistent clamping force or preload within assemblies where vibration and load cycling would otherwise cause fasteners or components to loosen over time. When a cup spring fatigues, cracks, or loses its profile, the assembly it supports can no longer maintain proper tension, leading to increased wear on surrounding parts or loss of operational precision in the affected system.
