The Bomag 05581138 Gas Spring is a genuine OEM component designed for the BMP 851 trench compactor. Sourced directly from Bomag, this gas spring meets the exact engineering specifications of the original part, ensuring a correct, trouble-free installation without guesswork. Operators running the BMP 851 can trust that this replacement matches the factory-installed unit in every critical dimension and performance characteristic.
Key Features
- Genuine OEM Calibrated Force Rating — matched to the precise extension force and damping profile Bomag specifies for the BMP 851, so the spring performs exactly as the original did from day one
- Direct Drop-In Replacement — engineered to the same mounting points, stroke length, and end fittings as the original, allowing straightforward installation on the BMP 851 trench compactor
- Verified BMP 851 Fitment — confirmed compatible with the BMP 851 remote-controlled trench compactor; part number 05581138 is the Bomag-designated replacement for this machine
- Sustained Controlled Movement — a correctly functioning gas spring maintains smooth, consistent resistance across its travel range, preventing abrupt or uncontrolled motion in the components it supports; a failed spring causes erratic or collapsed movement that accelerates wear on surrounding parts
- Sealed Pressurized Construction — the gas-charged cylinder resists contamination from the wet, muddy conditions typical of trench and backfill work, supporting a longer service life in demanding environments
A gas spring uses compressed nitrogen sealed inside a cylinder to generate a controlled, consistent extension force against a piston rod. On the BMP 851 trench compactor, it provides the resistance needed to hold or dampen the movement of access panels, linkages, or structural members, keeping components positioned correctly during operation and servicing. When a gas spring loses its charge or its seals fail, it can no longer support the load it was designed for, leading to drooping panels, uncontrolled movement, and potential damage to adjacent components — making timely replacement essential to keeping the machine operating safely and efficiently.
