Bomag Coupling | Part 05556102

The Bomag 05556102 Coupling is a genuine OEM component designed for Bomag cold milling machines and recycler/stabilizers, covering an extensive range of BM-series and MPH-series models including the BM 500/15, BM 1000/35, BM 2000/75, BM 2500/75, MPH 122, MPH 125, MPH 600, RS 460, RS 500, and RS 650, among others. Sourced directly from Bomag, this coupling meets the same engineering standards as the original unit fitted at the factory. This genuine OEM part ensures an exact match to the original connection interface, so installation is straightforward with no improvisation needed to achieve proper alignment. If you are servicing a BM-series cold milling machine or an MPH/RS-series recycler and stabilizer, part number 05556102 is the correct coupling to specify.

Key Features

• Genuine OEM Construction — manufactured to Bomag's original torque and dimensional tolerances, ensuring the coupling transmits drive loads exactly as the machine was engineered to deliver
• Direct-Fit Replacement — matches the original mounting configuration and connection profile across all listed BM-series and MPH/RS-series platforms, so the coupling seats and aligns correctly on the first attempt
• Broad Model Coverage — fits a wide range of Bomag cold milling machines (including BM 500/15, BM 600/15, BM 1000/35, BM 1200/35, BM 1300/35, BM 2000/75, BM 2200/75, and BM 2500/75) and recycler/stabilizers (including MPH 121, MPH 122, MPH 122-2, MPH 125, MPH 600, RS 460, RS 500, and RS 650)
• Drive Integrity Maintained — a worn or failed coupling can introduce vibration, slippage, or complete loss of drive transmission; replacing it with a correctly rated OEM unit restores smooth, uninterrupted power transfer to the cutting or mixing rotor
• Long-Term Fitment Confidence — as a genuine Bomag part, the part is validated against current and Stage V emissions-compliant variants, covering updated model designations such as BM 500/15 Stage V, BM 600/15 Stage V, and RS460 Stage V

A coupling connects two rotating shafts or drivetrain components, transferring torque from a power source — such as an engine or hydraulic motor — to the working assembly, whether that is a milling drum or a stabilizer rotor. It also accommodates minor misalignment between connected shafts and can absorb shock loads that would otherwise stress bearings and gearbox components. When a coupling wears, cracks, or fails entirely, the driven assembly loses power, vibration levels spike, and surrounding drivetrain components are put at risk of secondary damage — making prompt replacement critical to keeping the machine productive and protecting more expensive components downstream.
