The Bomag 05332902 Nilos Ring is a genuine OEM component designed for Bomag tandem rollers across the BW 80, BW 90, BW 100, BW 120, BW 125, BW 135, and BW 138 series. Sourced directly from Bomag, this ring delivers an exact OEM fit against the bearing assembly it protects, with no guesswork on compatibility. Confirmed fitment includes models such as the BW 80 AD-2, BW 90 AD-2, BW 100 AC-3, BW 100 AD-3, BW 120 AD-5, BW 125 ADH, BW 135 AD, BW 138 AD, and many more tandem roller variants. When a worn or damaged nilos ring lets contamination reach the bearing, premature bearing failure and costly repairs follow — replacing it with part number 05332902 restores the sealing integrity the bearing depends on.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Bomag's exact material and dimensional specification for the metal-faced contact seal, ensuring the ring seats flush and holds its retention against the bearing face
- Direct Drop-In Replacement — slots directly into the bearing position on compatible tandem rollers with the same bore geometry and face contact profile as the original, eliminating fitment uncertainty
- Broad Tandem Roller Coverage — confirmed fit across a wide range of Bomag tandem rollers including the BW 80 AD-2, BW 90 AD-5, BW 100 AD-5, BW 120 AD-5, BW 125 AC-4, BW 138 AC, and additional BW-series variants
- Bearing Contamination Defense — blocks ingress of dust, moisture, and fine debris at the bearing face, keeping the bearing running clean and extending service intervals on demanding compaction work
- Correct OEM Part Number — ordering by part number 05332902 eliminates the risk of receiving an incorrectly dimensioned ring that appears similar but fails to seat or seal properly
A Nilos ring is a thin, stamped-metal seal ring that fits directly against the face of a rolling-element bearing, acting as a labyrinth or contact shield between the bearing and its surrounding environment. Its job is to prevent abrasive particles, moisture, and other contaminants from entering the bearing's rolling surfaces, where even minor ingress causes accelerated wear, overheating, and eventual bearing seizure. When a Nilos ring becomes corroded, cracked, or loses its face contact, the bearing it protects is exposed — replacing this small component at the first sign of wear is far less costly than replacing the bearing assembly it shields.
