The Bomag 05581147 Gas Spring is a genuine OEM replacement designed for BW 177 and BW 178 series single drum rollers, including BW 177 D-3, BW 177 DH-3, BW 177 PDH-3, and BW 178 D-3 variants. Sourced directly from Bomag, this gas spring matches the original component in every dimension and pressure specification, ensuring a seamless installation with no guesswork. It fits the full range of BW 177 and BW 178 D-3 single drum roller configurations sold in both standard and USA-market specifications.
Key Features
- Genuine OEM Construction — built to the exact pressure rating and stroke length specified for BW 177 and BW 178 single drum rollers, ensuring consistent damping force from day one
- Direct Drop-In Replacement — matches the original mounting points and end fittings so this gas spring installs cleanly into the existing bracket without modification
- Broad BW 177 and BW 178 Coverage — compatible with BW 177 D-3, BW 177 DH-3, BW 177 PDH-3, BW 178 D-3, and their USA-market counterparts
- Sustained Holding Force — a properly functioning gas spring holds panels, hoods, or access covers securely in the open position, keeping operators safe during routine service and inspection
- Safe Access Assurance — a failed or weakened gas spring can allow heavy covers to drop unexpectedly; replacing it promptly restores controlled, hands-free panel support during maintenance
A gas spring is a sealed pneumatic strut that uses compressed gas to generate a consistent extension force, holding hoods, engine covers, or access panels open without the need for a prop rod. On heavy single drum rollers like the BW 177 and BW 178 series, these panels are substantial in weight, and the gas spring must deliver enough force to keep them safely elevated during inspections and fluid checks. When the internal seal wears or the gas charge depletes, the strut loses holding force and the panel can fall unexpectedly — making prompt replacement essential for safe machine maintenance.
