The Bomag 05570705 Pneumatic Spring is a genuine OEM component designed for BC-series refuse/landfill compactors and soil compactors, including the BC 672 RB, BC 772 RB, BC 772 RS, BC 972 RB, BC 1172 RB, and BC 772 EB-2. Sourced directly from Bomag, this pneumatic spring meets the same specifications as the part originally installed at the factory. It is compatible across both the standard and updated -2 generation variants, covering the BC 672 RB-2, BC 772 RB-2, BC 772 RS-2, BC 972 RB-2, and BC 1172 RB-2, making it a broad-coverage solution for fleets running multiple generations of these machines.
Key Features
- Genuine OEM Construction — engineered to the exact load-bearing and compression specifications Bomag requires for pneumatic suspension on heavy refuse and soil compactors, ensuring consistent damping behavior across the operating cycle
- Direct-Fit Replacement — matches the original mounting geometry and interface of the BC-series platform, so this pneumatic spring installs into position without modification to brackets or hardware
- Wide Generation Coverage — fits both standard and -2 generation BC 672 RB, BC 772 RB, BC 772 RS, BC 972 RB, and BC 1172 RB refuse/landfill compactors, as well as the BC 772 EB-2 soil compactor
- Sustained Cab and Chassis Isolation — a correctly functioning pneumatic spring absorbs shock and vibration transferred through the frame during compaction passes, protecting the operator environment and reducing stress on surrounding structural components
- Verified Part Number — order with confidence using Bomag part number 05570705, cross-referenced against the BC-series OEM catalog to confirm accuracy before the part ships
A pneumatic spring uses compressed air to support and cushion a load, functioning much like a conventional coil spring but with the ability to maintain consistent ride height and absorb variable shock loads more effectively. On heavy compactors like the BC-series, this component is typically used in cab suspension or chassis isolation systems, where it buffers the operator or structural assemblies from the intense impact forces generated during landfill and soil compaction work. When a pneumatic spring fails — losing pressure, cracking, or collapsing — the machine transmits far more vibration directly through the frame, accelerating wear on adjacent components and significantly degrading operator comfort and control.
