The Bomag 05850085 Hydraulic Cylinder is a genuine OEM component designed for Bomag single drum rollers including the BW 213 D-3, BW 213 DH-3, BW 213 PDH-3, BW 214 DH-3, BW 216 D-3, BW 216 DH-3, BW 219 DH-3, BW 219 PDH-3, BW 225 D-3, BW 225, BW 213 DH 3 VARIOCONTOL, BW 216 DHC-3, BW 213 DH-3 USA, BW 213 PDH-3 USA, and the C 850 C. Sourced directly from Bomag, this hydraulic cylinder carries the same part number 05850085 used in the original assembly, so you can install with confidence knowing the dimensions, porting, and stroke are built to the same specification as the unit it replaces. For fleet operators and service technicians managing high-hour Bomag single drum rollers, using a genuine OEM part is the straightforward way to restore hydraulic function without guesswork.
Key Features
- Genuine OEM Hydraulic Integrity — manufactured to Bomag's original pressure ratings and bore tolerances, ensuring the cylinder delivers consistent force and smooth actuation under the demanding load cycles of soil compaction work
- Direct Drop-In Replacement — matched port locations, mounting geometry, and rod dimensions allow this cylinder to seat correctly in the original mounting positions without rework or adaptation
- Broad Single Drum Roller Coverage — confirmed fit across BW 213, BW 214, BW 216, BW 219, and BW 225 series single drum rollers, as well as the C 850 C single drum roller
- Sustained Hydraulic Performance — a correctly functioning hydraulic cylinder maintains precise steering response and articulation control; a worn or leaking cylinder causes sluggish handling, fluid loss, and uneven compaction passes
- Verified Part Number Traceability — the OEM part number 05850085 matches Bomag's own service documentation, eliminating cross-reference errors when ordering for specific machine variants including USA-spec models
A hydraulic cylinder converts pressurized fluid into controlled linear movement, and on a single drum roller it typically governs articulation steering, drum offset, or auxiliary frame functions depending on its position in the machine. When the cylinder seal degrades or the barrel is damaged, the machine loses precise directional control or the ability to shift drum position, which directly affects compaction pattern accuracy and operator safety. Replacing a failed cylinder with a genuine OEM unit restores the original hydraulic circuit behavior and prevents the secondary damage that continued operation with a leaking cylinder can cause to pumps, valves, and hoses downstream.
