Wacker Neuson 5100011475 Nilos Ring

The Wacker Neuson Nilos Ring is a genuine OEM Nilos Ring designed for the RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 series tandem rollers, including standard, canopy, open-ROPS, DPF, and electric variants. As a direct Wacker Neuson OEM part, the is manufactured to the exact tolerances required for proper bearing protection in these machines. This part covers an extensive range of RD series configurations, making it the correct choice whether you're servicing a base model, a DPF-equipped unit, or one of the newer RD24e or RD28e electric variants.

Key Features

• OEM Bearing Seal Integrity — Manufactured to Wacker Neuson's exact dimensional tolerances, ensuring the metal enclosure lip seats correctly against the bearing race with no compromise to sealing performance.
• Direct Drop-In Replacement — Matches the original installed profile for RD series tandem rollers, fitting into the existing bearing housing without modification to adjacent components.
• Broad RD Series Compatibility — Fits RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 tandem rollers across standard, canopy, open-ROPS, DPF, and electric model variants.
• Protects Against Contamination-Driven Bearing Failure — A correctly functioning Nilos Ring keeps dirt, water, and compaction debris out of the bearing assembly — preventing the premature wear that leads to drum drive and vibration system failures.
• Genuine OEM Part — Sourced directly from Wacker Neuson, part number 5100011475 carries full OEM traceability for service records and fleet maintenance documentation.

A Nilos Ring is a pressed-metal bearing seal that fits flush against the outer or inner race of a roller bearing, forming a close-clearance labyrinth barrier that blocks contaminants from entering the bearing. In a tandem roller operating in dusty, wet, or abrasive compaction environments, this protection is critical — without it, grit and moisture penetrate the bearing, accelerating wear on the rolling elements and races. When a Nilos Ring becomes deformed, corroded, or displaced, bearing service life drops sharply, and left unaddressed, the result is bearing seizure and costly drum or drive system damage.
