The Bomag 78230102 Supporting Angle is a genuine OEM component designed for BW 120 AC-3, BW 120 AC-4, and BW 125 AC-4 tandem rollers. Sourced directly from Bomag, this supporting angle delivers the exact dimensions and material specification required for a correct, lasting installation. It fits all three tandem roller variants covered under part number 78230102, making it a straightforward, confidence-inspiring choice when completing structural or mounting repairs on your machine.
Key Features
- Genuine OEM Construction — manufactured to Bomag's exact material and dimensional standards, ensuring the structural integrity expected of a load-bearing angle bracket
- Direct Replacement Fit — engineered to mount in the original position without alteration, using the same hole pattern and profile as the factory component
- Confirmed Tandem Roller Compatibility — verified for the BW 120 AC-3, BW 120 AC-4, and BW 125 AC-4 tandem rollers
- Structural Stability — a correctly fitted supporting angle keeps attached assemblies properly aligned and secure, preventing stress on surrounding components during operation
- Long-Term Durability — genuine Bomag material grades resist deformation and fatigue under the vibration loads typical of tandem roller compaction work
A supporting angle is a structural bracket that braces or secures an assembly within the machine's frame, holding components in correct alignment and distributing mechanical loads across the mounting points. On a tandem roller, where constant vibration is generated through both drums during asphalt compaction passes, this type of bracket is critical to keeping attached systems stable and preventing premature wear on fasteners and adjacent parts. When a supporting angle becomes cracked, bent, or corroded, the components it holds can shift under load, accelerating wear and potentially causing secondary damage to nearby assemblies.
