The Bomag 05850048 Steering Cylinder is a genuine OEM component designed for Bomag BW-series tandem rollers, covering a wide range of 4th-generation models including the BW 141 AD-4, BW 151 AD-4, BW 161 AD-4, BW 190 AD-4, BW 202 AD-4, BW 203 AD-4, and BW 205 AD 4, among others. Sourced directly from Bomag, this steering cylinder meets the original engineering specifications for your machine — no guesswork on compatibility. It is the correct direct replacement for worn, damaged, or leaking cylinders across the tandem roller models listed, including AM, AC, ADH, ADO, and EU-Flex variants.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's original hydraulic tolerances, ensuring consistent steering response and correct operating pressure specific to BW-series tandem roller steering systems.
- Direct Drop-In Replacement — matches original mounting geometry, port configuration, and stroke length so this steering cylinder installs using standard service procedures without modification.
- Broad Tandem Roller Coverage — fits BW 141, BW 151, BW 154, BW 161, BW 190, BW 202, BW 203, and BW 205 series tandem rollers across AD-4, AC-4, ADH-4, ADO-4, AM, and EU-Flex variants.
- Restore Full Steering Control — a worn or failed steering cylinder causes sluggish, uneven, or unresponsive articulation, directly affecting pass quality and operator safety on the mat; this cylinder restores precise hydraulic articulation.
- Safety-Critical Steering Integrity — the steering cylinder is a primary safety component on articulated tandem rollers; using a genuine OEM part ensures hydraulic sealing and structural integrity meet the specifications your machine was designed around.
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. It converts hydraulic pressure from the steering circuit into controlled lateral movement, giving the roller the ability to follow curves and maintain precise tracking on asphalt passes. When the cylinder develops internal leakage, seal failure, or physical damage, steering becomes inconsistent or unresponsive — compromising both mat quality and safe machine operation.
