The Bomag 31780935 Sealing Ring is a genuine OEM component designed for a broad range of Bomag tandem rollers, single drum rollers, and pneumatic tyred rollers, including the BW 184 AD, BW 213 D-3, BW 213 PDH-3, BW 177 D-3, BW 177 DH-3, BW 180 AD, BW 178 D-3, BW 24 R, and C 850 C, among others. Sourced directly from Bomag, this sealing ring meets the same material and dimensional standards as the original part installed at the factory. This replacement installs directly into compatible Bomag roller models without modification, making it a straightforward service part for scheduled maintenance or unplanned repairs. Confirm your machine model against part number 31780935 before ordering to ensure correct fitment.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Bomag's original material and compression specifications, ensuring the sealing ring maintains proper fluid containment under operating pressures and temperatures specific to these roller models.
- Direct-Fit Replacement — dimensionally identical to the original, this sealing ring seats correctly in its mating groove or housing without trimming, adapting, or re-machining.
- Broad Roller Coverage — compatible with Bomag BW-series tandem rollers including the BW 184 AD and BW 180 AD, single drum rollers including the BW 213 D-3, BW 213 PDH-3, BW 177 DH-3, and BW 178 D-3, pneumatic tyred rollers including the BW 24 R, and HYPAC C-series rollers including the C 850 C.
- Leak Prevention at the Source — a correctly seated sealing ring prevents fluid intrusion or loss at its joint, protecting adjacent components from contamination and preserving system pressure for consistent roller performance.
- Fluid System Protection — a worn or degraded sealing ring allows leaks that can lead to hydraulic or lubricant loss; replacing it promptly with a genuine part maintains the integrity of the surrounding assembly and avoids escalating repair costs.
A sealing ring creates a pressure-tight barrier at the joint or bore where it is installed, preventing hydraulic fluid, oil, or other operational fluids from escaping the system. In rollers like the BW and C-series machines this part fits, maintaining that seal is critical to consistent hydraulic pressure, proper lubrication, and the protection of surrounding components. When a sealing ring deteriorates or is damaged, leaks develop that can quickly compromise system performance and lead to more extensive component wear if left unaddressed.
