The Bomag 05850047 Steering Cylinder is a genuine OEM component designed for BW 124-series and C 815-series single drum rollers, including the BW 124 DH-3, BW 124 PDH-3, BW 124 DH-4, BW 124 PDH-4, BW 124 DH-5, BW 124 PDH-5, and C 815 C single drum rollers. Sourced directly from Bomag, this steering cylinder matches the original unit in every dimension and specification, ensuring a direct, bolt-in installation with no guesswork. If your roller is pulling, responding sluggishly, or losing hydraulic pressure in the steering circuit, replacing this cylinder with part number 05850047 restores full operator control and safe machine handling.
Key Features
- Genuine OEM Hydraulic Integrity — manufactured to Bomag's original hydraulic pressure ratings and cylinder bore tolerances, so the steering circuit operates exactly as designed
- Direct Bolt-In Replacement — matches the original mounting points, port locations, and rod dimensions of the factory cylinder for a straightforward swap on BW 124 and C 815 single drum rollers
- Broad BW 124 Series Coverage — fits multiple generations including BW 124 DH-3, BW 124 DH-4, BW 124 DH-5, BW 124 PDH-3, BW 124 PDH-5, BW 124 DH-40, BW 124 PDH-40, and more
- Restored Steering Precision — a worn or leaking steering cylinder causes imprecise articulation and operator fatigue; this genuine replacement brings directional response back to the original standard
- Safety-Critical Component — steering system integrity directly affects machine control on grade and around jobsite hazards; using the correct OEM cylinder is essential for safe operation
The steering cylinder is the hydraulic actuator responsible for pivoting the articulated frame of the single drum roller, translating operator input at the steering wheel into precise directional movement of the machine. It works within a closed hydraulic circuit, extending and retracting under pressure to swing the rear frame left or right. When the cylinder develops internal leaks, scored seals, or damaged rod surfaces, steering becomes vague, inconsistent, or completely unresponsive — conditions that compromise both productivity and operator safety on any compaction site. Replacing a failed unit with a genuine Bomag steering cylinder like part number 05850047 ensures the hydraulic circuit returns to its original pressure capacity and response characteristics.
