The Bomag 05850303 Steering Cylinder is a genuine OEM component designed for BW 226 single drum rollers and BC-series soil compactors, including the BC 772 EB-2, BC 672 EB-2, BC 462 EB, BC 473 EB-3, BC 473 EB-4, and BC 772 EB-4. Sourced directly from Bomag, this steering cylinder is manufactured to the exact specifications of the original, ensuring a direct, confidence-inspiring replacement. This cylinder fits multiple BW 226 variants — including the BW 226 DH-4, BW 226 PDH-4, BW 226 DH-4i, BW 226 DH-5, BW 226 PDH-5, BW 226 DI-5, BW 226 RC-5, BW 226-5, BW 226 DH-4i EU-Flex, and BW 226 — covering a broad range of heavy compaction equipment in your fleet.
Key Features
- Genuine OEM Hydraulic Precision — manufactured by Bomag to exact bore tolerances and seal specifications, delivering the consistent hydraulic response a steering cylinder must have to control heavy single drum rollers and soil compactors effectively.
- Direct Bolt-On Replacement — matches the original mounting geometry and hydraulic port configuration, so this steering cylinder installs directly without rework or adaptation to existing brackets and lines.
- Broad Fleet Coverage — fits BW 226 single drum rollers across multiple generation variants and BC-series soil compactors including the BC 462 EB, BC 672 EB-2, BC 772 EB-2, BC 473 EB-4, and BC 772 EB-4, making it a practical stock item for mixed fleets.
- Restored Steering Responsiveness — a worn or leaking steering cylinder causes sluggish, imprecise articulation that undermines compaction pass accuracy and operator control; replacing it restores full, crisp steering authority on site.
- Safety-Critical Component — steering cylinders are directly responsible for machine directional control on heavy equipment; using a genuine OEM part ensures the cylinder meets the original pressure ratings and material standards for safe operation.
The steering cylinder is the hydraulic actuator that physically pivots the front and rear frames of an articulated machine relative to each other, translating operator input into directional movement. On heavy single drum rollers and soil compactors, this cylinder handles substantial side-loading forces during tight turns across uneven terrain, so its internal seals, bore finish, and end fittings must all perform within tight tolerances. When the cylinder begins to leak internally or externally — or loses the ability to hold position under load — steering becomes vague or unresponsive, compromising both compaction pattern accuracy and safe machine control.
