The Bomag 05850340 Steering Cylinder is a genuine OEM component designed for a broad range of Bomag single drum rollers and tandem rollers, including BW 213, BW 214, BW 216, BW 177, BW 212, BW 218, and BW 215 single drum rollers, as well as BW 161, BW 190, BW 202, BW 203, and BW 205 tandem rollers. Sourced directly from Bomag, this steering cylinder meets the same specifications as the original unit installed at the factory, ensuring a direct, exact-fit replacement with no guesswork. Confirmed fitment spans -40, -4, -4i, -5, and PL-series generation variants, covering a wide cross-section of the Bomag heavy roller fleet. When your current cylinder shows signs of drift, slow response, or hydraulic leak, replacing it with part number 05850340 restores full steering authority and keeps your machine operating safely on grade.
Key Features
- Genuine OEM Hydraulic Integrity — built to Bomag's hydraulic pressure and bore specifications, so the cylinder delivers consistent force output and seal life matched to your roller's steering circuit
- Direct Bolt-In Replacement — matches the original mounting geometry, port threads, and stroke length, allowing straightforward installation without machining or adapters
- Broad Roller Coverage — fits single drum roller models including BW 177, BW 212, BW 213, BW 214, BW 215, BW 216, and BW 218, plus tandem roller models including BW 161, BW 190, BW 202, BW 203, and BW 205 variants across multiple generation suffixes
- Responsive Steering Restored — a worn or leaking steering cylinder causes slow articulation response and pulling under load; this cylinder brings precise, proportional steering control back to the operator
- Steering System Safety — hydraulic steering is a primary safety system on articulated rollers; using an OEM-spec cylinder ensures the machine responds correctly under full compaction load and on sloped terrain
The steering cylinder is the hydraulic actuator that physically articulates the front and rear frames of a Bomag roller, translating input from the steering wheel into directional movement on the drum. It operates under continuous hydraulic pressure and must maintain a reliable seal to hold position and respond instantly to operator input — any internal leakage causes drift, wandering, or sluggish cornering that reduces compaction accuracy and creates a safety hazard. When the cylinder develops external leaks or internal bypass, the only reliable fix is replacement with a correctly spec'd unit like part number 05850340.
