The Bomag 02890402 Triangular Flange is a genuine OEM component designed for the BW 90 S walk-behind light roller. Sourced directly from Bomag, this triangular flange delivers the exact geometry and material grade required to maintain correct alignment and load transfer at its mounting interface. Contractors running BW 90 S equipment can order part number 02890402 with confidence, knowing it matches the original specification without any adaptation.
Key Features
- Genuine OEM Geometry — manufactured to Bomag's original dimensional tolerances, ensuring the flange seats flush and transfers load evenly at every bolt face
- Direct OEM Replacement — this triangular flange mounts to the same interface as the original, dropping in without rework or shimming
- Confirmed Fitment — verified for the BW 90 S walk-behind light roller; reference part number 02890402 when ordering to ensure an accurate match
- Structural Integrity Where It Counts — a correctly fitted triangular flange maintains proper load distribution across the mounting assembly; a worn or cracked flange risks misalignment and accelerated wear on surrounding components
- Long-Term Corrosion Resistance — OEM material selection provides the durability needed to withstand the vibration and environmental exposure typical of compaction work
A triangular flange serves as a rigid mounting and load-distribution interface within the roller's assembly, using its three-point contact geometry to spread clamping or transfer forces evenly rather than concentrating stress at a single point. On walk-behind rollers like the BW 90 S, this component plays a key role in keeping connected parts correctly aligned under continuous vibration. When a triangular flange cracks, distorts, or loses surface integrity, the uneven load path it creates can accelerate wear on bolts, bearings, and adjacent housings, leading to broader mechanical issues if left unaddressed.
