The Bomag 05331849 Nilos Ring is a genuine OEM bearing seal component designed for a range of BOMAG walk-behind light rollers, tandem rollers, and trench compactors. Sourced directly from BOMAG, this part meets the exact specifications required to maintain proper bearing protection across compatible machines. This Nilos Ring fits the BW 75 AD, BW 75 ADL, BW 75 AD-2, BW 75 E, BW 90 AD, BW 1050 T, BW 650 T, BW 850 T, BW 850 TR, and BW 85 T — making it a versatile sealing solution across BOMAG's light and trench compaction lineup. As a genuine OEM part, part number 05331849 delivers the precise dimensional tolerances needed to seat correctly against the bearing race and housing without adjustment or modification.
Key Features
- Genuine OEM Bearing Seal Integrity — manufactured to BOMAG's exact tolerancing, ensuring the metal-encased seal seats flush against the bearing race for effective contamination exclusion
- Direct Drop-In Replacement — engineered to match the original Nilos Ring geometry, allowing installation directly into the existing bearing assembly without reworking the housing
- Broad BOMAG Fitment — compatible with BW 75 AD, BW 75 ADL, BW 75 AD-2, BW 75 E, BW 90 AD, BW 1050 T, BW 650 T, BW 850 T, BW 850 TR, and BW 85 T machines
- Bearing Contamination Protection — a correctly fitted Nilos Ring blocks debris, moisture, and fine particles from entering the bearing; a damaged or missing ring accelerates bearing wear and leads to premature failure
A Nilos Ring is a metal axial sealing washer that fits directly against the side face of a rolling-element bearing, forming a close-clearance shield between the rotating and stationary components. Its primary role is to prevent dirt, grit, and moisture from infiltrating the bearing while retaining lubrication inside the assembly. When a Nilos Ring is worn, deformed, or missing entirely, contaminants enter the bearing freely — accelerating raceway wear, increasing operating temperatures, and ultimately causing bearing seizure that can sideline the machine.
