The Bomag 05581181 Gas Spring is a genuine OEM component designed for BW 177 and BW 211 series single drum rollers, including the BW 177 D-40, BW 177 DH-40, BW 177 PDH-40, BW 177 D-50, BW 177 DH-50, BW 177 PDH-50, BW 211 D-50, and BW 211 PD-50. Sourced directly from Bomag, this gas spring matches the original specification for a straightforward, bolt-in installation with no guesswork. It is the correct choice when an original-equipment replacement is required to restore proper hood, door, or access panel support on these machines.
Key Features
- Genuine OEM Gas Pressure Rating — manufactured to Bomag's original pressure and stroke specification, ensuring consistent extension force that holds panels securely open under real working conditions
- Direct Bolt-In Replacement — end fittings and mounting geometry match the original mounting points on BW 177 and BW 211 single drum rollers, dropping straight into place without modification
- Broad Single Drum Roller Coverage — confirmed fit across the BW 177 D-40, BW 177 DH-40, BW 177 PDH-40, BW 177 D-50, BW 177 DH-50, BW 177 PDH-50, BW 211 D-50, and BW 211 PD-50
- Sustained Panel Control — a correctly charged gas spring holds access panels at full extension, keeping hands free during inspections and fluid checks; a worn or leaking unit allows panels to drop unexpectedly
- Operator Safety — a failed gas spring that allows a heavy engine hood or access door to fall poses a direct injury risk; replacing it with a genuine part restores the controlled, positive hold the machine was built with
A gas spring is a sealed pneumatic strut that uses compressed gas — typically nitrogen — to generate a controlled, consistent extension force. On Bomag single drum rollers, the gas spring supports engine hoods, service access doors, or inspection panels, holding them open at a fixed position while operators perform maintenance or inspections. When the internal seal degrades or the gas charge bleeds off over time, the spring loses its holding force and panels can drop suddenly, creating a safety hazard and interrupting service work. Replacing a worn gas spring with a genuine Bomag part restores the original holding force and ensures safe, hands-free access to the machine.
