The Wacker Neuson 5100012246 is a genuine OEM Nilos Ring designed for the RD24, RD27, and RD28 series tandem rollers. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component installed at the factory. It fits a wide range of RD24-100 and RD28-120 configurations — including open-drum, combination, DPF, and electric variants — as well as the RD27-120 series. Whether you are servicing a standard RD24-100, an RD28-120c DPF, or an RD27-120 O Tandem Roller, part number 5100012246 is the correct replacement.
Key Features
- Genuine OEM Bearing Seal Integrity — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring the ring seats and seals correctly against the bearing face without gaps or distortion.
- Drop-In Replacement — Installs directly in place of the original Nilos Ring with no modification to surrounding bearing components or housings required.
- Broad RD-Series Compatibility — Confirmed fitment across the RD24-100, RD27-120, and RD28-120 tandem roller families, including open-drum, combination-drum, DPF, and electric-drive variants.
- Bearing Protection Where It Counts — A correctly functioning Nilos Ring keeps contaminants out of the bearing cavity and retains lubrication; a worn or missing ring accelerates bearing wear and can lead to premature bearing failure on the drum drive system.
- Verified OEM Part Number — Cross-reference 5100012246 against your Wacker Neuson parts manual or service documentation to confirm the correct application before installation.
A Nilos Ring is a metal-backed sealing ring pressed against the face of a roller bearing to protect it from dirt, water, and debris while retaining bearing grease or oil within the housing. In tandem rollers like the RD24, RD27, and RD28, the drum drive and exciter shaft bearings operate in harsh compaction environments where contamination is constant. When the Nilos Ring wears, cracks, or is dislodged, the bearing loses its protective barrier — grease escapes, abrasive particles enter, and bearing service life drops sharply. Replacing a damaged Nilos Ring promptly is one of the lowest-cost ways to protect a high-value bearing assembly.
