The Bomag 05900636 Inner Coupling is a genuine OEM component designed for Bomag BM 2000/75, BM 2200/75, BM 2000/75 TE, BM 2500/75, BM2000/65 Stage V, and BM2200/65 Stage V cold milling machines. Sourced directly from Bomag, this inner coupling delivers an exact OEM fit with no guesswork on compatibility. If your milling machine is showing signs of drivetrain vibration, coupling wear, or power transfer issues, replacing this component with a genuine part restores the mechanical integrity the machine was built with.
Key Features
- Genuine OEM Coupling Integrity — manufactured to Bomag's exact torque transfer and dimensional tolerances, ensuring the coupling engages and seats exactly as the original did
- Direct OEM Replacement — installs in place of the original inner coupling with no modification, matching the mounting interface and coupling geometry of the OEM assembly
- Broad Cold Milling Machine Coverage — fits the BM 2000/75, BM 2200/75, BM 2000/75 TE, BM 2500/75, BM2000/65 Stage V, and BM2200/65 Stage V cold milling machines
- Sustained Power Transfer — a correctly functioning inner coupling maintains smooth, consistent torque delivery to the milling drum; a worn or failed coupling leads to power loss, excessive vibration, and accelerated wear on surrounding drivetrain components
- Verified Part Number Fit — order with confidence using Bomag part number 05900636 to confirm you have the right component for your machine before it arrives on site
The inner coupling is a core drivetrain component that transmits rotational force between connected shafts or assemblies within the milling machine's powertrain. It acts as the mechanical link that keeps torque flowing smoothly from the drive source to the milling drum system, absorbing minor misalignment and shock loads in the process. When an inner coupling wears, cracks, or fails, the result is vibration, erratic drum behavior, and potential damage to adjacent components — making timely replacement critical to keeping the machine cutting efficiently and accurately.
