Key Features
- Genuine OEM Gear Geometry — manufactured to Bomag's exact tooth profile and material spec, ensuring proper mesh, load transfer, and gear engagement without compromise
- Direct Drivetrain Replacement — installs in place of the original ring gear with no adaptation, maintaining correct torque transmission through the drive assembly
- Confirmed Fitment — verified for the BW 120 AD tandem roller per Bomag's official parts documentation, eliminating guesswork at ordering time
- Restored Power Transfer — a worn or damaged ring gear causes slipping, vibration, and loss of drive force; this replacement restores full, consistent power delivery to the drum
- Drivetrain Longevity — OEM-grade steel and heat treatment protect against wear under the cyclic loading demands of asphalt compaction work
The ring gear is a core drivetrain component that transmits rotational force from the drive motor or gearbox to the drum or axle assembly. It works in mesh with a pinion gear to multiply torque and transfer power through the drivetrain. When a ring gear wears, chips, or cracks, the result is audible grinding, inconsistent drum rotation, or complete loss of drive — all of which halt compaction work and can cause secondary damage to surrounding drivetrain components. Replacing a failed ring gear promptly with the correct OEM part restores smooth, reliable power transmission and protects the integrity of the surrounding gear assembly.
