The Bomag 05850411 Steering Cylinder is a genuine OEM component designed for Bomag BW 161, BW 190, BW 191, BW 202, and BW 206 series tandem rollers. Sourced directly from Bomag, this steering cylinder meets the same engineering standards as the original unit installed at the factory. It delivers an exact hydraulic and mechanical fit across the full range of compatible AD-5, AC-5, AD-50, and ADO-5 variants, ensuring proper articulation response and operator control. If you are cross-referencing by part number, confirm compatibility using part number 05850411 against your machine's serial number and model designation.
Key Features
- Genuine OEM Hydraulic Integrity — manufactured to Bomag's original pressure ratings and bore tolerances, ensuring the steering circuit operates at the correct flow and force characteristics for tandem roller applications
- Direct-Fit Replacement — port connections, rod dimensions, and mounting interfaces match the original cylinder exactly, allowing straightforward installation without machining or modification
- Broad Tandem Roller Coverage — fits BW 161, BW 190, BW 191, BW 202, and BW 206 tandem rollers across AD-5, AC-5, AD-50, ADO-5, and ADO-50 variants, including the BW 206 AD-5 AM
- Restored Steering Precision — a worn or leaking steering cylinder causes sluggish articulation, steering drift, and reduced pass accuracy on asphalt; this cylinder restores full hydraulic authority and predictable machine tracking
- Operational Safety — steering system integrity is critical on ride-on tandem rollers operating close to paving crews; an OEM-spec cylinder maintains the hydraulic response needed for safe, controlled maneuvering
The steering cylinder is the hydraulic actuator that controls articulation between the front and rear frames of a tandem roller, translating operator input into precise directional movement of the machine. It works within the closed-loop hydraulic steering circuit, extending and retracting under pressure to pivot the chassis and guide the drums along the intended compaction path. When the cylinder develops internal leakage, seal failure, or physical damage, steering becomes unresponsive or erratic — compromising both mat quality and jobsite safety — making timely replacement essential to keeping the machine under full operator control.
