The Bomag 87610209 Back-Up Ring is a genuine OEM component designed for Bomag pavers, tandem rollers, and cold milling machines across multiple model families, including the BF 800 and BF 900 paver series, BW 154 and BW 174 tandem rollers, and BM 500/15 and BM 600/15 cold milling machines. Sourced directly through Bomag's authorized parts supply chain, this back-up ring meets the original engineering specification for a direct, drop-in fit. Confirm your model against the fitment list before ordering to ensure this is the correct part for your machine.
Key Features
- Genuine OEM Sealing Integrity — manufactured to the original material grade and dimensional tolerance required for hydraulic or rotary seal applications on Bomag equipment, ensuring the ring maintains proper compression and fluid containment
- Direct-Fit Replacement — engineered to the same cross-section and diameter as the original, so this back-up ring seats correctly in its groove without rework or shimming
- Broad Model Coverage — fits BF 800 C and BF 900 C pavers, BW 154 and BW 174 tandem rollers, and BM 500/15 and BM 600/15 cold milling machines, including Stage V and EU-Flex variants
- Leak Prevention — a correctly installed back-up ring prevents seal extrusion under pressure, protecting hydraulic circuits from fluid loss and contamination that can lead to costly downstream repairs
- Authorized Part Number Traceability — ordering by part number 87610209 ensures you receive the correct Bomag-specified component, eliminating the risk of cross-referencing errors when servicing multiple machine types
A back-up ring is a supporting seal element used alongside primary O-rings in hydraulic or pneumatic assemblies. Its job is to prevent the softer O-ring from extruding into the clearance gap between mating components when pressure is applied — a failure mode that causes rapid seal degradation and fluid leaks. When a back-up ring becomes brittle, cracked, or deformed, the primary seal loses its support and can fail prematurely, leading to hydraulic fluid loss, reduced actuator performance, and potential damage to surrounding components. Replacing this ring at the first sign of wear or during any seal service is essential to maintaining the hydraulic integrity of the machine.
