The Bomag 05581157 Gas Spring is a genuine OEM component designed for a wide range of Bomag refuse/landfill compactors, recycler/stabilizers, and cold milling machines — including the BC 972 RB, BC 1172 RB, MPH 121, MPH 122, and BM 500/15 Stage V. Sourced directly from Bomag, this gas spring meets the same specifications as the original part installed at the factory. It is a direct-fit replacement for covered models including the BC 972 RB-2, BC 1172 RB-2, MPH 122-2, BM 600/15 Stage V, BM 500/15-2, and BM 600/15-2, ensuring straightforward installation with no guesswork on compatibility.
Key Features
- Genuine OEM Pressure Integrity — manufactured to Bomag's original pressure and stroke specifications, so this gas spring delivers the consistent extension force the application demands without risk of premature pressure loss
- Drop-In Replacement — engineered to the original mounting dimensions and end-fitting configuration, this part installs directly into the existing bracket points on covered machines
- Broad Model Coverage — fits BC 972 RB, BC 972 RB-2, BC 1172 RB, and BC 1172 RB-2 refuse/landfill compactors; MPH 121, MPH 122, and MPH 122-2 recycler/stabilizers; and BM 500/15 Stage V, BM 600/15 Stage V, BM 500/15-2, and BM 600/15-2 cold milling machines
- Controlled Access and Operator Safety — a properly functioning gas spring holds access panels, hoods, or covers securely open during service, preventing uncontrolled closure that can injure technicians working on the machine
- Long Service Life — OEM-grade seals and cylinder materials resist the dust, vibration, and temperature cycles typical of compactor and milling machine environments, maintaining damping performance across the component's full service interval
A gas spring is a sealed pneumatic strut that uses compressed gas — typically nitrogen — to generate a controlled, consistent pushing or holding force across its stroke. On heavy equipment like refuse compactors, recyclers, and cold milling machines, gas springs are commonly used to prop open engine hoods, service covers, and access doors, keeping them securely raised while operators or technicians work underneath. When a gas spring loses pressure or its seals degrade, the supported panel can drop suddenly and without warning, creating a serious safety hazard and disrupting routine maintenance. Replacing a failed gas spring with a genuine Bomag part restores the safe, predictable operation that crews depend on during daily service checks and repair work.
