The Bomag 05576121 Spring is a genuine OEM component designed for BW 142 D-2, BW 172 D-2, and BW 212 D-2 single drum rollers, as well as the BC 601 RB refuse/landfill compactor. Sourced directly from Bomag, this spring matches the exact material grade, rate, and geometry of the original — so it seats and functions the way the machine was engineered to perform. Verified fitment across these four Bomag models means you can order with confidence, knowing this part installs without modification or guesswork.
Key Features
- Genuine OEM Spring Rate and Geometry — manufactured to the exact load rating and dimensional spec of the original, ensuring the spring delivers consistent tension or return force throughout its service life
- Direct Drop-In Replacement — engineered to the same seating dimensions and end configuration as the factory component, so installation is straightforward on all covered machines
- Broad Verified Fitment — confirmed for the BW 142 D-2, BW 172 D-2, and BW 212 D-2 single drum rollers and the BC 601 RB refuse/landfill compactor
- Sustained Mechanical Reliability — a spring that has lost its rated tension or cracked under fatigue affects actuator response, valve operation, or return timing; this genuine replacement restores correct function immediately
- Authentic Bomag Part — carries the Bomag OEM designation, confirming it meets the same quality controls as the component installed at the factory
A spring serves as a critical mechanical element that stores and releases energy to maintain tension, return a component to its neutral position, or hold parts in consistent contact under load. In heavy compaction equipment like single drum rollers and refuse compactors, springs appear throughout valve assemblies, linkages, and actuator mechanisms where precise force and reliable return movement are essential to machine control. When a spring fatigues, loses its rated load capacity, or breaks entirely, the component it governs can stick, respond sluggishly, or fail to seat correctly — leading to erratic machine behavior and accelerated wear on surrounding parts. Replacing a worn spring promptly with a genuine OEM part like the Bomag 05576121 keeps the affected assembly operating within its designed parameters.
