The Wacker Neuson 5100011988 is a genuine OEM Greasing Nipple designed for the RD18 series tandem rollers, including the RD18-80, RD18-100, and RD18-100C. As a genuine OEM component, the 5100011988 is manufactured to the same specification as the original part installed at the factory, ensuring a direct, hassle-free installation. This nipple fits across the full RD18 lineup, covering standard, US, SE, and C variants, making it the go-to replacement for fleet operators running multiple RD18 configurations. Keep a spare on hand to stay on top of scheduled greasing intervals and protect your machine's moving components.
Key Features
- Genuine OEM Construction: — Threaded to the exact pitch and material spec of the original, ensuring consistent grease flow and a leak-free seal at the fitting point.
- Direct Installation: — Threads directly into the original grease port with no rework or adapter required, accepting a standard grease gun coupler.
- Broad RD18 Series Coverage: — Compatible with RD18-80, RD18-100, and RD18-100C tandem rollers across standard, US, SE, and C configurations.
- Protects Critical Bearing and Pivot Points: — A functional greasing nipple is essential for delivering lubrication to drum bearings, eccentric shafts, and articulation joints — a failed or clogged nipple leads to dry running and accelerated wear on expensive internal components.
- Low-Cost Maintenance Item, High-Value Protection: — Replacing a damaged or stripped greasing nipple at service time is one of the most cost-effective steps you can take to extend component life on a tandem roller.
A greasing nipple — also called a grease fitting or zerk fitting — is the access point through which pressurized grease is injected into a bearing housing, pivot joint, or rotating assembly. On a tandem roller like the RD18 series, these fittings serve drum bearings, articulation joints, and eccentric mechanisms that endure constant vibration and load. When a greasing nipple is damaged, stripped, or blocked, grease cannot reach the components it is meant to protect, causing metal-on-metal wear that can lead to premature bearing failure or seized joints. Replacing a worn fitting promptly keeps your lubrication intervals effective and your machine running as intended.
