The Bomag 05850066 Steering Cylinder is a genuine OEM component designed for Bomag BW 141 AD-2, BW 144 AD-2, BW 151 AC-2, BW 151 AD-2, BW 154 AD-2, and BW141AD 2 tandem rollers. Sourced directly from Bomag, this steering cylinder matches the exact hydraulic specifications and mounting dimensions of the original unit. Confirmed fitment across the BW 140- and BW 150-series tandem roller line means you can install with confidence and get your machine back on the mat without second-guessing compatibility.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's exact bore tolerances and pressure ratings, ensuring consistent hydraulic force and smooth articulation under working loads
- Direct-Mount Replacement — matches the original cylinder's port locations, rod diameter, and end-fitting geometry for a clean drop-in installation on compatible tandem rollers
- Broad Tandem Roller Coverage — confirmed fit for BW 141 AD-2, BW 144 AD-2, BW 151 AC-2, BW 151 AD-2, BW 154 AD-2, and BW141AD 2 tandem rollers, covering multiple variants in the series
- Restored Steering Response — a correctly functioning steering cylinder delivers crisp, proportional articulation so the operator can hold tight rolling passes and maintain grade on asphalt surfaces
- Operational Safety — a leaking or failed steering cylinder compromises directional control on a ride-on tandem roller; replacing with a genuine OEM unit restores the hydraulic integrity the machine's steering circuit depends on
The steering cylinder is the hydraulic actuator responsible for articulating the front and rear frames of a tandem roller relative to each other, allowing the operator to steer the machine across the work surface. When hydraulic pressure is applied, the cylinder extends or retracts to pivot the articulation joint, translating operator input into smooth directional changes. A worn or damaged steering cylinder can cause sluggish steering response, hydraulic fluid loss, or a complete loss of directional control — any of which will take the machine out of service and create a safety hazard on an active paving site.
