The Bomag 05231141 Taper Roller Bearing is a genuine OEM component designed for Bomag BW-series single drum rollers and the MPH 121 recycler/stabilizer. Sourced directly from Bomag, this bearing delivers the exact dimensional tolerances and load ratings required to keep drum and drivetrain assemblies running within specification. Confirmed fitment spans a wide range of single drum roller models including the BW 142 D-2, BW 172 D-2, BW 145 D-3, BW 145 DH-3, BW 145 PDH-3, BW 177 D-3, BW 177 DH-3, BW 178 D-3, and the C 825 C, as well as the MPH 121 recycler/stabilizer.
Key Features
- Genuine OEM Load Rating — manufactured to Bomag's exact radial and axial load specifications for taper roller bearing applications in compaction and stabilization equipment
- Drop-In Fitment — matches the original bearing geometry and seating dimensions, so installation goes straight in without machining or shimming
- Broad Model Coverage — fits BW 142 D-2, BW 172 D-2, BW 145 D-3, BW 177 D-3, BW 178 D-3, BW 145 DH-3, BW 145 PDH-3, BW 177 DH-3, C 825 C single drum rollers, and the MPH 121 recycler/stabilizer
- Sustained Drum Performance — a correctly seated taper roller bearing maintains proper drum alignment and even compaction force; a worn bearing causes vibration, uneven roller loading, and accelerated wear on surrounding components
- Verified Part Number — order with confidence using Bomag part number 05231141, confirmed against Bomag's OEM catalog for the listed machines
A taper roller bearing is engineered to handle both radial loads — forces pushing perpendicular to the shaft — and axial thrust loads that run along the shaft's length. In a single drum roller, these bearings are commonly used in drum hubs, drive axles, and transmission assemblies where the machine's compaction forces and drive torque place simultaneous demands on the bearing. When a taper roller bearing begins to fail, operators typically notice increased vibration, noise from the drum or drivetrain, and heat buildup at the bearing housing. Left unaddressed, a failed bearing can damage shafts, housings, and adjacent components, turning a straightforward bearing swap into a far more costly repair. Replacing this bearing with the correct Bomag 05231141 OEM part restores proper load distribution and protects the integrity of the surrounding assembly.
