Key Features
- Genuine OEM Retention Integrity — Manufactured by Wacker Neuson to maintain the precise tension and seating characteristics required for secure component retention in tandem roller assemblies.
- Drop-In Fitment — Engineered to seat directly into the original groove or housing without reworking, keeping the service process straightforward and efficient.
- Broad RD-Series Compatibility — Fits a wide range of Wacker Neuson tandem rollers spanning the RD18-100 C through RD45-140 series, including C, O, DPF, US-market, and .3-generation variants.
- Consistent Retention Under Load — A correctly installed spring ring holds rotating or sliding components firmly in place; a worn or failed ring allows axial movement that accelerates wear on surrounding parts.
- Verified Part Number — Order with confidence using Wacker Neuson part number 5100012377 to confirm you are receiving the correct ring for your specific machine configuration.
A spring ring — also known as a snap ring or circlip — is a fastening component that seats into a machined groove on a shaft or inside a bore to retain bearings, gears, or other assemblies in their correct axial position. On tandem rollers like the Wacker Neuson RD series, these rings are found throughout the drivetrain, drum, and vibration system to keep critical components locked in place during operation. When a spring ring becomes fatigued, deformed, or loses its tension, the retained component can shift or disengage entirely, leading to accelerated wear, unusual noise, or mechanical failure of the assembly it was securing.
