The Bomag 05712945 Main Bearing is a genuine OEM component designed for BC-series refuse and landfill compactors and the MPH 121 recycler/stabilizer. Sourced directly from Bomag, this main bearing meets the same specifications as the original part installed at the factory. Confirmed fitment covers the BC 571 RB, BC 671 RB, BC 671 RS, BC 772 RB, BC 772 RS, BC 972 RB, BC 1172 RB, BC 672 RB, and the MPH 121.
Key Features
- Genuine OEM Tolerancing — manufactured to Bomag's exact dimensional and load-rating specifications for a main bearing, ensuring correct journal fit and rated load capacity without compromise
- Drop-In Replacement — engineered to the same housing dimensions and shaft interface as the original, allowing this bearing to seat correctly without reworking bearing bores or journals
- Broad BC-Series and MPH Coverage — fits the BC 571 RB, BC 671 RB, BC 671 RS, BC 772 RB, BC 772 RS, BC 972 RB, BC 1172 RB, BC 672 RB refuse/landfill compactors, and the MPH 121 recycler/stabilizer
- Drivetrain Integrity Restored — a worn or failed main bearing leads to excessive shaft play, heat buildup, and accelerated wear on surrounding drivetrain components; replacing it promptly keeps the machine operating at rated output
- Authentic Part Number Traceability — ordering by Bomag part number 05712945 confirms you receive the correct bearing grade and geometry for these demanding heavy compaction applications
A main bearing is a critical rotating component that supports the crankshaft or primary drive shaft, carrying both radial and axial loads generated during machine operation. It maintains precise shaft alignment inside the housing, which is essential for smooth power transfer and even wear across connected drivetrain components. When a main bearing begins to fail — through contamination, fatigue, or inadequate lubrication — operators typically notice increased vibration, abnormal noise, and rising operating temperatures, all of which signal the need for immediate replacement to prevent more extensive mechanical damage.
