The Bomag 05728803 Pillow Block is a genuine OEM component designed for the BMP 851 trench compactor. Sourced directly from Bomag, this pillow block delivers an exact fit to the original mounting configuration, ensuring proper shaft alignment and bearing support are restored to spec. If your BMP 851 is showing signs of shaft misalignment, unusual vibration, or premature bearing wear, replacing this component with the correct OEM part is the right call. Confirm part number 05728803 against your machine's service documentation before ordering to ensure a match to your serial range.
Key Features
- OEM Bearing Housing Precision — manufactured to Bomag's original tolerances, ensuring correct bore alignment and shaft load distribution specific to the BMP 851 drivetrain
- Direct-Mount Replacement — matches the original bolt pattern and housing geometry so this pillow block installs into the existing mounting position without rework
- BMP 851 Trench Compactor Fitment — confirmed fitment for the BMP 851, Bomag's remote-controlled articulated trench compactor built for confined-space soil compaction
- Sustained Shaft Support — a correctly functioning pillow block keeps the rotating shaft centered and properly loaded; a worn or cracked housing accelerates bearing failure and can lead to shaft damage
- Genuine Bomag OEM Part — backed by Bomag's OEM supply chain, so you get the same material grade and dimensional spec as the part that came off the factory floor
A pillow block is a self-contained bearing housing unit that mounts a rotating shaft to a fixed surface, providing radial support while accommodating slight misalignment. On the BMP 851 trench compactor, the pillow block plays a key role in keeping drivetrain and compaction-system shafts running true under the sustained dynamic loads these machines generate. When a pillow block housing cracks, corrodes, or loses its dimensional accuracy, the bearing it houses can shift out of position — leading to accelerated wear, vibration, and eventual shaft or bearing failure that takes the machine out of service.
