The Wacker Neuson 5100011937 is a genuine OEM Nilos Ring designed for the RD18-80 and RD18-100 series tandem rollers, including the RD18-80, RD18-80 SE, RD18-80.3, RD18-100, RD18-100 SE, RD18-100.3, RD18-100c, and RD18-100c.3 variants. As a direct Wacker Neuson OEM component, part 5100011937 is manufactured to the same specification as the original, ensuring a correct, reliable installation in your RD18 series machine. This Nilos Ring is a precision sealing washer that sits directly against the bearing race, making exact fitment critical to proper bearing protection and drum performance on your tandem roller.
Key Features
- Genuine OEM Bearing Seal Integrity — Manufactured by Wacker Neuson to the same material and dimensional specification as the original, ensuring the stamped metal lip seats flush against the bearing race with no gaps that could allow contaminant ingress.
- Direct Installation Fit — Engineered to drop into the existing bearing position on RD18 series drum assemblies without reworking or shimming — the profile matches the original mounting interface exactly.
- Broad RD18 Series Coverage — Confirmed fitment across the full RD18-80 and RD18-100 family, including SE, US, .3, c, and c.3 variants, covering both standard and special-edition walk-behind tandem roller configurations.
- Bearing Protection Where It Counts — A correctly seated Nilos Ring keeps compaction debris, water, and fine aggregate out of the drum bearing. A worn or missing ring allows contamination that accelerates bearing wear and leads to drum instability on the asphalt surface.
A Nilos Ring is a pressed-steel sealing washer with a flexible lip that presses against the side face of a rolling-element bearing to block contaminants from entering the bearing cavity. In a tandem roller like the RD18 series, the drum bearings operate in a demanding environment — vibration, water, and fine asphalt particles are constantly present — so keeping those bearings sealed is essential to smooth drum rotation and consistent compaction output. When a Nilos Ring deforms, corrodes, or goes missing, contaminants work into the bearing, causing premature wear, rough drum rotation, and eventually bearing failure that can take the machine out of service entirely.
