Key Features
- OEM Bearing Seal Integrity — manufactured to Bomag's exact material and dimensional specifications, ensuring the Nilos Ring delivers the correct axial sealing pressure against the bearing race
- Direct-Fit Replacement — engineered to seat flush against the bearing face on the BW 120 AD, installing the same way as the original with no reworking of adjacent components
- Confirmed Fitment — verified for BW 120 AD tandem rollers, so you can order with confidence that this is the correct part for your machine
- Bearing Protection Where It Counts — a correctly seated Nilos Ring keeps contaminants out of the bearing and lubricant in, directly supporting drum and drivetrain bearing service life
- Genuine Bomag OEM Quality — sourced from Bomag's authorized parts supply, this component meets the same standard as the ring installed at the factory
A Nilos Ring is a stamped metal axial sealing ring fitted directly against the face of a rolling-element bearing. Its primary job is to act as a labyrinth-style barrier, preventing grease or oil from escaping the bearing cavity while blocking dirt, water, and debris from working their way in. On a tandem roller like the BW 120 AD, bearings in the drum, vibratory, and drivetrain assemblies are exposed to water, slurry, and compaction forces during every pass — making a properly seated Nilos Ring essential to bearing longevity. When this ring is worn, deformed, or missing, contamination enters the bearing rapidly, leading to premature wear, increased heat, and eventual bearing failure that can sideline the machine.
