The Bomag 05337320 Nilos Ring is a genuine OEM component designed for the BW 212 D-2 single drum roller. Sourced directly from Bomag, this replacement sealing ring matches the original specification, ensuring it seats correctly against the bearing face without alteration or fitting issues. If your BW 212 D-2 is showing signs of bearing contamination or lubricant loss, replacing the Nilos Ring is a straightforward step that restores proper bearing protection and extends service life.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Bomag's original material and dimensional specification, delivering the same metal-backed sealing performance as the factory-installed ring
- Direct Bearing-Face Fit — pressed to the correct profile for direct installation against the bearing race on the BW 212 D-2, with no rework or shimming needed
- Confirmed Fitment — verified for the BW 212 D-2 single drum roller; use part number 05337320 to ensure you receive the correct ring for your machine
- Bearing Contamination Defense — shields the bearing from dirt, moisture, and abrasive particles that are common on compaction worksites, helping maintain smooth drum operation under load
- Lubricant Retention — the close-fitting metal ring retains grease at the bearing interface, preventing the dry-running conditions that accelerate bearing wear and lead to costly replacements
A Nilos ring is a thin, stamped-metal sealing element that fits directly against the face of a rolling-element bearing. Its primary job is to retain lubricant inside the bearing cavity while keeping contaminants — dirt, water, and fine debris — from working their way in. On a machine like the BW 212 D-2 single drum roller, bearings are constantly exposed to vibration, mud, and grit, making this small component critical to long-term bearing health. When a Nilos ring deteriorates or is damaged, grease escapes and contaminants enter, accelerating wear on the bearing races and rolling elements and eventually leading to bearing failure.
