The Bomag 05711158 Main Bearing is a genuine OEM component designed for a wide range of Bomag single drum rollers and tandem rollers, including the BW 172 D-2, BW 145 D-3, BW 124 DH-4, BW 151 AD-4, and BW 138 AD, among others. Sourced directly from Bomag, this main bearing is manufactured to the same specification as the original part it replaces, ensuring a true drop-in fit with no guesswork on compatibility. It is verified for use across the BW single drum and tandem roller lines, as well as C 815 C and C 825 C single drum rollers, making it a versatile service part for mixed fleets. When it comes time to rebuild or restore a critical engine or drivetrain assembly, part number 05711158 is the correct OEM choice.
Key Features
- Genuine OEM Precision Tolerancing — manufactured to exact dimensional and load-rating specifications for the bearing journals in Bomag roller powertrains, ensuring correct clearance and load distribution from the first hour of operation
- Direct OEM Replacement — matches the original mounting dimensions and surface finish, installing directly into the bearing housing without reworking or shimming
- Broad Fleet Coverage — fits BW-series single drum rollers including the BW 172 D-2, BW 145 D-3, BW 124 DH-4, and BW 124 PDH-3, as well as tandem rollers including the BW 151 AD-4, BW 141 AD-4, BW 154 AD-4, BW 138 AD, BW 120 AD-3, and C 815 C and C 825 C single drum rollers
- Crankshaft and Journal Protection — a correctly functioning main bearing keeps the crankshaft centered and spinning freely; a worn bearing causes knocking, oil pressure loss, and accelerated crankshaft damage that can lead to full engine failure
- OEM Part Number Confidence — order with confidence using Bomag part number 05711158, matching the bearing to the correct machine without cross-referencing aftermarket catalogs
The main bearing is a precision-fit component that supports the crankshaft within the engine block, maintaining the correct running clearance between the crankshaft journals and the bearing housing. It carries the load generated by combustion and keeps the crankshaft rotating smoothly under the high pressures of a working engine. When a main bearing wears or fails, it typically presents as low oil pressure, a deep knocking noise at idle, or in severe cases a seized or damaged crankshaft — making timely replacement with a correctly specified part essential to restoring full engine health.
