Bomag 05850469 Hydraulic Cylinder

The Bomag 05850469 Hydraulic Cylinder is a genuine OEM component designed for Bomag cold milling machines, including the BM 1000/35, BM 1200/35, BM 1300/35, BM 1200/35 T4f, BM 1300/35 T4f, BM 1000/35-2, BM1200/35-2, and BM1000/35-2. Sourced directly from Bomag, this hydraulic cylinder matches the original engineering specifications, ensuring a straight swap with no guesswork on fitment. Whether you are restoring a milling machine after hydraulic failure or completing a scheduled rebuild, this component delivers the exact performance characteristics the machine was designed around.

Key Features

• Genuine OEM Hydraulic Integrity — manufactured to Bomag's original pressure ratings and stroke tolerances, so the cylinder performs exactly as the cold milling machine's hydraulic circuit demands
• Direct-Swap Replacement — matches the original mounting geometry, port sizing, and rod diameter of the factory unit, allowing straightforward installation without machining or adapter fittings
• Broad Cold Milling Machine Coverage — fits the BM 1000/35, BM 1200/35, BM 1300/35, BM 1200/35 T4f, BM 1300/35 T4f, BM 1000/35-2, BM1200/35-2, and BM1000/35-2, covering multiple generations of Bomag's mid-size milling lineup
• Restored Cutting Depth Control — a properly functioning hydraulic cylinder maintains precise drum height and cutting depth adjustment, keeping the milling pass accurate and consistent across the full working width
• Sealing and Pressure Retention — OEM-spec internal seals resist hydraulic fluid degradation and maintain operating pressure under the sustained load cycles typical of continuous milling operations

The hydraulic cylinder on a cold milling machine is responsible for raising and lowering the milling drum assembly, controlling cutting depth, and in many configurations, managing the machine's height relative to the road surface. When the cylinder develops internal leaks or seal failure, the operator loses precise depth control, which leads to inconsistent milling profiles and potential damage to the surrounding pavement. Replacing a worn or failed cylinder with a genuine Bomag part — such as part number 05850469 — restores full hydraulic authority over the drum position, allowing the machine to deliver the flat, accurate milled surface that downstream paving operations depend on.
