The Bomag 05573021 Pillow Block is a genuine OEM component designed for Bomag BC 473 RB-4, BC 473 RB-3, BC 473 RS-4 refuse and landfill compactors, BC 473 EB-4 and BC 473 EB-3 soil compactors, and MPH 600 3B/4i-PB and RS 650 recyclers and stabilizers. As a direct OEM replacement, this pillow block delivers the exact housing geometry and bearing alignment the machine was built around. Sourced directly from Bomag, part number 05573021 ensures you are installing the same component specified at the factory. Whether you are servicing a refuse compactor or a recycler/stabilizer, this part confirms fitment across the full range of compatible machines.
Key Features
- OEM Bearing Housing Precision — Manufactured to Bomag's exact bore tolerances and housing dimensions, ensuring the bearing seats correctly and runs true under heavy cyclical loads.
- Drop-In Replacement Fit — Matches the original mounting bolt pattern and shaft alignment of the BC 473 and MPH 600 3B/4i-PB platforms for a straightforward swap with standard shop tooling.
- Broad Machine Coverage — Fits BC 473 RB-4, BC 473 RB-3, BC 473 RS-4 refuse/landfill compactors, BC 473 EB-4 and BC 473 EB-3 soil compactors, and MPH 600 3B/4i-PB and RS 650 recyclers/stabilizers.
- Sustained Load-Bearing Performance — A correctly installed pillow block maintains proper shaft support and rotation under the vibration and shock loads typical of compaction and stabilization work, preventing premature bearing wear and shaft misalignment.
- Genuine Bomag Part — Supplied as authentic Bomag OEM stock under part number 05573021, eliminating fit uncertainty and supporting consistent machine uptime across demanding job cycles.
A pillow block is a housed bearing unit that supports a rotating shaft at a fixed point on the machine's frame or chassis. It combines an outer housing — typically cast iron or steel — with an inner bearing that allows the shaft to spin freely while absorbing radial and axial loads transmitted during operation. On heavy compaction and recycling equipment like the BC 473 series and MPH 600 3B/4i-PB, pillow blocks are subjected to constant vibration and impact stress; a worn or cracked housing allows the shaft to shift out of alignment, which accelerates bearing failure, increases drivetrain wear, and can lead to unplanned machine downtime. Replacing a failed pillow block with the correct OEM unit restores proper shaft support and protects the surrounding drivetrain components.
