The Bomag 05850560 Steering Cylinder is a genuine OEM component designed for Bomag tandem rollers across the BW 80, BW 90, BW 100, BW 120, and BW 138 series, including the BW 80 AD-5, BW 90 AD-5, BW 100 AD-5, BW 120 AD-5, BW 138 AD-5, and BW 138 AC-5, among others. Sourced directly from Bomag, this steering cylinder matches the original component exactly — same dimensions, same hydraulic specs, same mounting interface. This genuine OEM part is the correct choice when articulation response and steering precision matter on your asphalt crew. Confirmed fitment spans the full fifth-generation tandem roller lineup, covering AC, AD, SC, SL, SLC, ADM, ACM, and ADe variants to keep your fleet covered with a single verified part number 05850560.
Key Features
- Genuine OEM Hydraulic Integrity — manufactured to Bomag's original hydraulic pressure tolerances and cylinder bore specifications, ensuring consistent force output and smooth articulation through the full steering arc.
- Direct Bolt-On Replacement — retains the factory mounting points and hydraulic port orientation of the original steering cylinder, allowing a clean swap without machining or adapter fittings.
- Broad Fifth-Generation Tandem Roller Coverage — fits BW 80 AD-5, BW 90 AD-5, BW 90 AC-5, BW 100 AD-5, BW 100 AC-5, BW 100 ADM-5, BW 100 ACM-5, BW 100 SCC-5, BW 100 SC-5, BW 100 SL-5, BW 100 ADe-5, BW 120 AD-5, BW 120 AC-5, BW 120 SL-5, BW 120 SLC-5, BW 120SL-5, BW 120 ADe-5, BW 120 AD-5 CC, BW 135 AD-5, BW 138 AC-5, and BW 138 AD-5 tandem rollers.
- Steering Accuracy Restored — a worn or leaking steering cylinder causes sluggish articulation, uneven pass alignment, and operator fatigue; this cylinder restores tight, responsive steering control for accurate asphalt laydown.
- Hydraulic System Safety — a failed steering cylinder can result in loss of directional control on an operating roller; replacing it with a correctly rated OEM cylinder maintains the machine's hydraulic steering integrity and operator safety.
The steering cylinder is the hydraulic actuator that controls articulation between the front and rear frames of the tandem roller — when the operator turns the steering wheel, hydraulic pressure extends or retracts this cylinder to pivot the machine through the turn. It is a load-bearing, pressure-rated component that must maintain a leak-free seal under continuous working pressure to deliver consistent, proportional steering response. When the cylinder develops internal leaks, seal failures, or physical damage, steering becomes vague or unresponsive, making accurate mat alignment difficult and creating a potential safety hazard on the jobsite.
