The Bomag 57003954 Pillow Block is a genuine OEM component designed for BC 772 RB-2, BC 772 RB-4, BC 772 RS-4, and BC 672 RB-4 refuse and landfill compactors. Sourced directly from Bomag, this pillow block delivers the exact dimensional tolerances and load ratings required for proper shaft support on these heavy-duty machines. Correct fitment is confirmed for all four compactor configurations, giving fleet operators and service technicians confidence when ordering replacement hardware for scheduled maintenance or unplanned repairs.
Key Features
- OEM Bearing Housing Integrity — manufactured to Bomag's original specifications, ensuring the correct bore diameter, bolt pattern, and housing material grade for sustained shaft alignment under compaction loads
- Drop-In Replacement — matches the original mounting footprint on BC 772 and BC 672 refuse compactors, allowing direct installation without modification to brackets or fastener positions
- Broad Refuse Compactor Coverage — fits the BC 772 RB-2, BC 772 RB-4, BC 772 RS-4, and BC 672 RB-4, covering multiple generation and configuration variants across Bomag's heavy landfill compactor line
- Sustained Shaft Support Under Load — a properly seated pillow block maintains shaft concentricity during high-cycle compaction work; a worn or misaligned housing accelerates bearing failure and leads to uneven drum or roller operation
- Genuine Bomag Part — supplied as an authentic OEM component under part number 57003954, verified against Bomag's parts catalog for these refuse and landfill compactor models
A pillow block is a mounted bearing housing that supports a rotating shaft at a fixed point on the machine's frame or structure. It holds the inner bearing assembly in precise alignment so the shaft can spin freely while carrying radial and axial loads generated during compaction cycles. When the housing wears, cracks, or loses its seating integrity, the bearing inside shifts out of alignment — accelerating wear on both the bearing and the shaft itself, and ultimately causing vibration, noise, or catastrophic shaft failure if left unaddressed.
