The Bomag 05818127 Orifice is a genuine OEM component designed for Bomag single drum rollers across the BW 177, BW 178, BW 211, BW 212, BW 213, BW 214, BW 215, BW 216 series and the C 850 C single drum roller. Sourced directly from Bomag, this orifice meets the precise dimensional and flow tolerances required by the original hydraulic system design. It fits an extensive range of generation variants — including -3, -4, -40, -4i, and -50 builds — making it the correct choice for a wide spread of machines in active fleets. When it is time to restore proper hydraulic function to your roller, part number 05818127 is the verified OEM solution.
Key Features
- OEM-Calibrated Flow Tolerance — manufactured to Bomag's exact orifice bore specification, ensuring consistent hydraulic flow restriction across all operating conditions
- Direct Drop-In Replacement — matches the original thread form, body diameter, and seat geometry for a straightforward installation with no rework to surrounding hydraulic fittings
- Broad Single Drum Roller Coverage — fits BW 177, BW 178, BW 211, BW 212, BW 213, BW 214, BW 215, and BW 216 series single drum rollers, including the C 850 C, spanning generation -3 through -50 variants
- Hydraulic System Integrity — a worn or undersized orifice disrupts pressure regulation and flow damping, leading to erratic drum vibration control and accelerated wear on downstream hydraulic components; this orifice restores correct system behavior
An orifice is a precision-bored hydraulic fitting that controls the rate of fluid flow between circuits by restricting passage to a fixed, calibrated diameter. In a single drum roller's hydraulic system, orifices are used to regulate pressure build-up, dampen shock loads, and sequence valve actuation — functions that directly affect drum vibration performance and drive responsiveness. When an orifice erodes, becomes blocked, or is incorrectly sized, hydraulic pressure can become unstable, causing loss of vibration amplitude control or sluggish machine response; replacing it with a correctly specified OEM part restores the system to its designed operating parameters.
