The Bomag 05818024 Sealing Ring is a genuine OEM component designed for Bomag BW 120 AD and BW 138 AC tandem rollers, as well as BW 1050 T, BW 850 TR, and BW 85 T trench compactors. Sourced directly from Bomag, this sealing ring matches the original part in material grade, dimensional tolerances, and compression characteristics — so it seats correctly the first time. Confirmed fitment across both tandem roller and trench compactor applications makes part number 05818024 a straightforward, stock-matching replacement for service technicians and equipment operators alike.
Key Features
- Genuine OEM Material Grade — manufactured to Bomag's original compound and dimensional spec, ensuring the sealing ring delivers the same compression and sealing performance as the factory-installed part
- Drop-In Replacement Fit — engineered to the same cross-section and seat geometry as the original, allowing direct installation without rework or custom fitting
- Broad Bomag Fitment — compatible with BW 120 AD and BW 138 AC tandem rollers and BW 1050 T, BW 850 TR, and BW 85 T trench compactors, covering a range of Bomag compaction equipment
- Leak Prevention Where It Counts — a properly seated sealing ring keeps hydraulic or fluid circuits closed and pressurized; a worn or cracked ring leads to fluid loss, contamination, and potential component damage
- Fluid System Integrity — correct sealing is critical to maintaining safe operating pressures within the machine's hydraulic or drive systems; using an OEM-spec ring supports proper system function
A sealing ring creates a pressure-tight barrier between mating components in a machine's hydraulic, fluid, or drive system, preventing leaks and keeping contaminants out of sensitive assemblies. In tandem rollers and trench compactors, these seals are exposed to continuous vibration, pressure cycling, and temperature changes, all of which degrade the ring material over time. When a sealing ring fails, fluid loss and contamination can follow quickly — leading to overheating, loss of drive performance, or damage to surrounding components — making timely replacement essential to keeping the machine operational.
