The Bomag 05850544 Steering Cylinder is a genuine OEM component designed for BW 219 and BW 220 series single drum rollers. Sourced directly from Bomag, this steering cylinder meets the original engineering specifications for hydraulic pressure tolerances, bore dimensions, and seal integrity. It delivers an exact fit across a wide range of BW 219 variants — including the BW 219 D-4, BW 219 D-5, BW 219 DH-4, BW 219 PDH-4, BW 219 PD-4, BW 219 DH-5, BW 219 PDH-5, BW 219 PD-5, and BW 220 D-4 — making it a straightforward service replacement with no guesswork on compatibility.
Key Features
- Genuine OEM Hydraulic Precision — engineered to Bomag's original pressure ratings and cylinder bore specifications, ensuring proper steering force and hydraulic response for single drum roller operation
- Direct Drop-In Replacement — matches the original mounting points, port locations, and stroke length so this steering cylinder installs directly into BW 219 and BW 220 single drum rollers without modifications
- Broad BW 219 and BW 220 Coverage — confirmed fitment across BW 219 D-4, BW 219 D-4i, BW 219 DH-4, BW 219 DH-4i, BW 219 PDH-4, BW 219 PDH-4i, BW 219 PD-4, BW 219 DH-4i EU-Flex, BW 219 D-5, BW 219 D-5 PL, BW 219-5, BW 219 DH-5, BW 219 PDH-5, BW 219 PD-5, BW 220 D-4, and BW 220 D-40
- Restored Steering Control — a worn or failing steering cylinder causes sluggish, inconsistent, or unresponsive articulation; replacing it restores full hydraulic steering authority and machine maneuverability on the compaction pass
- Safety-Critical Fitment — steering system integrity is essential for operator safety and grade control on large single drum rollers; using the correct OEM cylinder ensures the hydraulic circuit operates within designed pressure limits
The steering cylinder is a hydraulic actuator that controls the articulation joint between the front and rear frames of the single drum roller, allowing the operator to steer the machine across the compaction surface. It converts hydraulic pressure from the steering circuit into precise lateral movement, giving the operator directional control at working speed and during tight turns. When this cylinder develops internal leaks, seal failures, or physical damage, steering becomes heavy, erratic, or fails entirely — creating both a productivity loss and a serious safety concern that requires immediate attention.
