The Bomag 05850055 Steering Cylinder is a genuine OEM component designed for Bomag MPH and RS series recyclers and stabilizers. Sourced directly from Bomag, this steering cylinder meets the original engineering specifications required to maintain precise steering control on these large-format machines. This part fits the MPH 121, MPH 122, MPH 122-2, MPH 125, MPH 600, MPH 600 3B/4i-PB, MPH 600 EU-FLEX, RS 460, RS 500, and RS 650 recycler/stabilizer models. When steering response matters on the job, installing an authentic replacement like this cylinder is the only reliable choice.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's original specifications, ensuring the correct bore diameter, stroke length, and seal compatibility for consistent hydraulic steering performance
- Direct Bolt-In Replacement — engineered to match the original mounting points and hydraulic port configuration, allowing straightforward installation on compatible recycler/stabilizer models
- Broad MPH and RS Series Coverage — fits MPH 121, MPH 122, MPH 122-2, MPH 125, MPH 600, MPH 600 3B/4i-PB, MPH 600 EU-FLEX, RS 460, RS 500, and RS 650 recyclers and stabilizers
- Restored Steering Accuracy — a fully functioning steering cylinder delivers the hydraulic force needed for responsive directional control, keeping the machine tracking correctly during passes
- Operational Safety — the steering cylinder is a safety-critical component; a failed or leaking cylinder can cause loss of directional control on heavy recycler/stabilizer equipment, making prompt replacement with a verified OEM part essential
The steering cylinder is a hydraulic actuator that converts hydraulic pressure into the mechanical force needed to turn the machine's front axle or articulation joint, giving the operator directional control over the machine. On large recyclers and stabilizers like the MPH and RS series, this cylinder handles substantial loads during each steering input, and the integrity of its seals and rod are critical to maintaining responsive, leak-free operation. When a steering cylinder begins to fail — through seal degradation, rod scoring, or internal bypass — the machine may exhibit slow steering response, fluid leaks, or complete loss of steering authority, all of which create serious safety and productivity concerns on site.
