The Bomag 05331228 Nilos Ring is a genuine OEM component designed for Bomag vibratory plates and walk-behind rollers, including the BP 20/48 D, BP 23/48 D, BP 23/60 D, BPR 30/38 D, BW 55, BW 55 E, and BW 75 E. Sourced directly from Bomag, this ring delivers an exact match to the original specification — no guesswork on fit or compatibility. It is the correct replacement for machines where the original Nilos ring has worn, deformed, or compromised bearing protection.
Key Features
- Genuine OEM Bearing Protection — manufactured to Bomag's original tolerances, ensuring the metallic sealing ring seats correctly against the bearing face and maintains its designed sealing geometry
- Direct Drop-In Replacement — part number 05331228 matches the original installation profile, fitting the bearing housing without rework or adaptation
- Broad Bomag Fitment — confirmed for BP 20/48 D, BP 23/48 D, BP 23/60 D, BPR 30/38 D vibratory plates and BW 55, BW 55 E, BW 75 E walk-behind rollers
- Shields Bearings from Contamination — the Nilos ring excludes dirt, water, and debris from the bearing cavity, directly extending bearing service life in demanding compaction environments
- Prevents Costly Bearing Failure — a worn or missing ring allows contaminants into the bearing, accelerating wear and leading to unplanned machine downtime on compaction jobs
A Nilos ring is a thin metallic axial seal that fits flush against the face of a rolling-element bearing, acting as a first line of defense against dirt, water, and fine particles entering the bearing cavity. In compaction equipment like vibratory plates and walk-behind rollers, the operating environment is especially harsh — constant vibration and ground contact throw up abrasive material that can rapidly degrade an unprotected bearing. When the Nilos ring is worn or missing, contaminants bypass the bearing seal, accelerate wear on the rolling elements and races, and eventually cause bearing failure that takes the machine out of service. Replacing this ring at the correct service interval is a straightforward step that protects a significantly more expensive bearing assembly.
