The Bomag 05900546 Ring Gear is a genuine OEM component designed for Bomag BM-series cold milling machines, including the BM1300/30, BM1200/30, BM1000/30-2, BM1300/30-2, BM1200/30-2, BM1300/30-T3, and BM1200/30-T3. Sourced directly from Bomag, this ring gear matches the original in tooth profile, material grade, and dimensional tolerances — so it drops in exactly where the worn or damaged gear came out. Compatible coverage spans multiple generations of these cold milling machines, making part number 05900546 a straightforward solution for scheduled rebuilds or unplanned drivetrain repairs.
Key Features
- Genuine OEM Tooth Geometry — manufactured to Bomag's original tooth profile and hardness specifications, ensuring correct mesh and load transfer within the milling drivetrain
- Direct Replacement Fit — matches the original mounting dimensions and bore, allowing installation without machining or adaptation
- Broad BM-Series Coverage — fits BM1300/30, BM1200/30, BM1000/30-2, BM1300/30-2, BM1200/30-2, BM1300/30-T3, and BM1200/30-T3 cold milling machines
- Drivetrain Integrity Restored — a worn ring gear causes rough engagement, accelerated wear on mating components, and loss of milling torque; replacing it promptly protects surrounding drivetrain parts
- OEM Parts Traceability — supplied under part number 05900546 with full Bomag OEM sourcing, supporting accurate service records and parts documentation
The ring gear is a core element of the milling drum drive system, transmitting rotational force from the drive motor to the cutting drum with precise gear engagement. When the ring gear wears or cracks, the machine loses consistent torque delivery to the drum, leading to uneven milling depth, increased vibration, and accelerated wear on the pinion and bearing assemblies. Replacing this component with a genuine Bomag part restores proper power transfer and protects the surrounding drivetrain from secondary damage.
