The Bomag 05850406 Hydraulic Cylinder is a genuine OEM hydraulic cylinder designed for BC-series soil compactors and refuse/landfill compactors, including the BC 772 EB-2, BC 772 EB-4, BC 572 RB-2, BC 672 RB-2, BC 672 RB-3, BC 672 RB-4, BC 772 RB-2, BC 772 RB-3, and BC 772 RB-4. Sourced directly from Bomag, this cylinder is manufactured to the exact dimensions and tolerances of the original component it replaces. This hydraulic cylinder fits both soil compactor and refuse/landfill compactor variants across multiple BC-series generations, making it a dependable choice for fleet operators managing mixed BC-series equipment.
Key Features
- OEM Bore and Seal Tolerances — manufactured to Bomag's original hydraulic specifications, ensuring proper operating pressure containment and full stroke travel without internal leakage
- Direct-Mount Replacement — matches the original mounting points, port locations, and rod dimensions of the factory-installed cylinder for a straightforward swap
- Broad BC-Series Coverage — fits BC 772 EB-2, BC 772 EB-4 soil compactors and BC 572 RB-2, BC 672 RB-2, BC 672 RB-3, BC 672 RB-4, BC 772 RB-2, BC 772 RB-3, and BC 772 RB-4 refuse/landfill compactors
- Consistent Hydraulic Force Output — a correctly functioning cylinder maintains the precise actuation force these heavy compactors depend on for steering, articulation, or implement control; a worn or leaking cylinder causes sluggish response and uncontrolled drift
- Genuine Bomag Part — part number 05850406 is an authentic OEM component, not a generic substitute, ensuring material grade and wall thickness match the original design intent
A hydraulic cylinder converts pressurized hydraulic fluid into linear mechanical force, moving critical machine systems such as the articulation joint, blade, or ejector mechanism through a controlled push or pull stroke. On heavy BC-series compactors, these cylinders handle substantial loads cycle after cycle, and degraded seals or a scored bore will cause pressure loss, fluid bypass, and loss of precise control. Replacing a failing cylinder with a genuine OEM unit like the Bomag 05850406 restores full hydraulic force and responsive machine control, preventing secondary damage to pumps and valves caused by operating under low-pressure conditions.
