The Bomag 05331326 Nilos Ring is a genuine OEM component designed for BW 55 E and BW 55 walk-behind light rollers. Sourced directly from Bomag, this nilos ring delivers an exact, OEM-spec fit with no guesswork on compatibility. It is confirmed to fit both the BW 55 E and BW 55, making it the correct choice for operators servicing either machine. When it comes to bearing protection components, genuine OEM quality ensures the sealing performance your roller depends on.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Bomag's exact material and dimensional spec, ensuring the nilos ring seats correctly and delivers full bearing protection from the moment it is installed
- Direct OEM Replacement — this nilos ring installs in place of the original without rework or adaptation, restoring the bearing assembly to its designed operating condition
- Confirmed Fitment — compatible with Bomag BW 55 E and BW 55 walk-behind light rollers; part number 05331326 is the correct OEM reference for these machines
- Bearing Protection Where It Counts — a properly functioning nilos ring keeps contaminants and moisture away from the bearing race, preventing premature bearing wear and costly drivetrain damage
- Long-Term Bearing Life — using the correct OEM nilos ring maintains the precise axial clearance the bearing requires, avoiding the uneven loading that worn or mismatched rings can cause
A nilos ring is a metal sealing washer that fits against the outer face of a rolling-element bearing, forming a labyrinth-style barrier that blocks dirt, water, and debris from entering the bearing race. On walk-behind rollers like the BW 55 E and BW 55, bearings operate in demanding outdoor conditions where contamination is constant, making this small component critical to bearing service life. When a nilos ring is worn, deformed, or missing, contaminants reach the bearing directly — accelerating wear, generating heat, and leading to premature bearing failure that takes the machine out of service.
