Bomag 05850226 Piston

The Bomag 05850226 Piston is a genuine OEM component designed for BC-series refuse/landfill compactors and soil compactors, including the BC 571 RB, BC 671 RB, BC 771 RB, BC 572 RB-2, BC 672 RB-2, BC 772 RB-2, BC 672 EB-2, BC 772 EB-2, BC 672 RB-3, BC 772 RB-3, BC 672 RB-4, BC 772 RB-4, and BC 772 EB-4. Sourced directly from Bomag, this piston is built to the same specification as the part it replaces, ensuring a correct fit within the engine or hydraulic assembly with no guesswork on compatibility. Verified by part number 05850226 against Bomag's OEM catalog, this component gives fleet managers and service technicians confidence that they are installing the right part the first time.

Key Features

• Genuine OEM Precision — manufactured to Bomag's exact dimensional and material tolerances, ensuring the piston seats, seals, and cycles correctly within the assembly it serves
• Direct Drop-In Replacement — engineered to the same specification as the original, this piston installs into the host assembly using existing hardware and mating surfaces without rework
• Broad BC-Series Coverage — confirmed fitment across BC 571 RB, BC 671 RB, BC 771 RB, BC 572 RB-2, BC 672 RB-2, BC 772 RB-2, BC 672 EB-2, BC 772 EB-2, BC 672 RB-3, BC 772 RB-3, BC 672 RB-4, BC 772 RB-4, and BC 772 EB-4 — covering both refuse/landfill compactor and soil compactor variants
• Sustained Compaction Output — a correctly functioning piston maintains proper pressure and stroke consistency, keeping the machine delivering the compaction force these heavy-duty BC-series units are rated for; a worn or failed piston causes pressure loss and erratic operation
• Pressure Integrity Under Load — the tight dimensional tolerancing of a genuine OEM piston is critical in high-load compactor applications where pressure loss from wear or poor fit directly affects machine output and cycle reliability

A piston is a core reciprocating component within an engine cylinder or hydraulic actuator, converting pressure — whether combustion gases or hydraulic fluid — into mechanical force and motion. In heavy compactors like the BC-series, the piston must maintain a consistent seal against cylinder walls to sustain the pressure required for reliable power delivery or actuator movement. When a piston wears, scores, or fails, the assembly loses compression or hydraulic efficiency, resulting in reduced output, increased operating temperatures, and potential damage to surrounding components if left unaddressed.
