The Bomag 31780469 Sealing Ring is a genuine OEM component designed for a wide range of Bomag tandem rollers, single drum rollers, and pneumatic tyred rollers, including the BW 184 AD, BW 180 AD, BW 213 D-3, BW 212 D-3, BW 177 D-3, BW 177 DH-3, BW 177 PDH-3, BW 178 D-3, BW 211-40, BW 24 R, C 560 B, and C 850 C. Sourced directly from Bomag, this sealing ring matches the original specification exactly, ensuring a proper fit without modification. As a genuine OEM part, it delivers the same material integrity and dimensional accuracy as the component installed at the factory, maintaining the sealing performance your machine depends on.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Bomag's original material and dimensional spec, ensuring the correct compression and seal performance for hydraulic and mechanical interfaces on these roller models
- Direct Drop-In Replacement — engineered to the same profile and tolerances as the original, so this sealing ring seats correctly in its groove without rework or adaptation
- Broad Roller Coverage — fits Bomag BW-series tandem rollers including the BW 184 AD and BW 180 AD, single drum rollers including the BW 213 D-3, BW 212 D-3, BW 177 D-3, BW 177 DH-3, BW 177 PDH-3, BW 178 D-3, and BW 211-40, plus the C 850 C single drum roller and pneumatic tyred rollers BW 24 R and C 560 B
- Leak Prevention — a correctly seated sealing ring prevents fluid loss and contamination ingress, keeping hydraulic pressure stable and protecting surrounding components from premature wear
- Verified Part Number Fit — order with confidence using Bomag part number 31780469, cross-referenced to the machines listed above for accurate identification
A sealing ring creates a pressure-tight barrier between mating surfaces or around rotating and reciprocating components, preventing fluid from escaping and contaminants from entering a system. On compaction rollers, sealing rings are used throughout hydraulic circuits, wheel drive assemblies, and vibratory drum systems where maintaining fluid containment is critical to machine function. When a sealing ring deteriorates, cracks, or is displaced, fluid leaks develop, hydraulic pressure drops, and surrounding components are exposed to contamination — leading to accelerated wear and potential system failure.
