The Bomag 05815709 Oil Seal is a genuine OEM component designed for BW 120 AD tandem rollers and BW 1050 T, BW 850 TR, and BW 85 T trench compactors. Sourced directly from Bomag, this oil seal matches the original part in material grade, dimensional tolerancing, and sealing performance — ensuring a correct, lasting installation. Whether you are servicing a BW 120 AD on an asphalt crew or maintaining a BW 1050 T or BW 85 T trench compactor in the field, this is the exact seal the machine was built with. Verify compatibility using part number 05815709 before ordering.
Key Features
- OEM Sealing Material Grade — manufactured to Bomag's original elastomer and hardness specifications, delivering the compression characteristics this application demands
- Direct-Fit Replacement — dimensionally identical to the original, seating correctly into the housing bore without reworking or shimming
- Confirmed Fitment — part number 05815709 is verified for the BW 120 AD tandem roller and BW 1050 T, BW 850 TR, and BW 85 T trench compactors
- Leak Prevention — a properly seated oil seal keeps lubricant contained and contaminants out, protecting bearings and rotating assemblies from premature wear
- Genuine Bomag OEM Part — supplied as an authentic Bomag replacement, so fit, function, and longevity match what the machine was engineered for
An oil seal creates a dynamic barrier between a rotating shaft and its surrounding housing, retaining lubrication fluid on one side while blocking dirt, moisture, and debris from entering on the other. In machines like tandem rollers and trench compactors, where drum drives and eccentric shafts operate under sustained load and vibration, a sound oil seal is essential to keeping internal components properly lubricated. When an oil seal deteriorates — cracking, hardening, or losing its sealing lip — oil migrates out and contaminants migrate in, accelerating bearing and shaft wear and leading to more extensive component damage if left unaddressed.
