The Bomag 05939021 Angular Joint is a genuine OEM component designed for Bomag tandem rollers across the BW 80, BW 90, BW 100, BW 120, BW 135, and BW 138 series. As a direct OEM replacement, this angular joint delivers the exact fit and material specification required to restore proper articulation and control to your machine. Compatible models include the BW 80 AD-5, BW 90 AD-5, BW 90 AC-5, BW 100 AD-5, BW 100 AC-5, BW 100 ADM-5, BW 100 ACM-5, BW 100 SCC-5, BW 120 AD-5, BW 120 AC-5, BW 135 AD-5, BW 138 AD-5, and BW 138 AC-5 tandem rollers. Sourced directly from Bomag, this part carries the full confidence of genuine OEM quality — built to the same specification as the original.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original material and dimensional specifications, ensuring the angular joint performs exactly as the machine was engineered to operate
- Direct Bolt-In Replacement — engineered to match the original mounting geometry and connection points, allowing straightforward installation without modification
- Broad Tandem Roller Coverage — fits BW 80 AD-5, BW 90 AD-5, BW 90 AC-5, BW 100 AD-5, BW 100 AC-5, BW 100 ADM-5, BW 100 ACM-5, BW 100 SCC-5, BW 120 AD-5, BW 120 AC-5, BW 135 AD-5, BW 138 AD-5, and BW 138 AC-5 tandem rollers
- Restored Steering Response — a properly functioning angular joint maintains smooth, accurate articulation; a worn or failed joint introduces play and imprecise steering that compromises compaction pass quality
- Verified Part Number Traceability — order with confidence using Bomag part number 05939021, cross-referenced to the correct fitment for the models listed above
The angular joint is a critical linkage component in the articulated steering system of a tandem roller. It transfers rotational and angular movement between connected shafts or steering linkages, allowing the machine to articulate smoothly through turns while maintaining consistent force transfer. When an angular joint wears out or fails, operators will notice increased steering slop, vibration through the control circuit, or uneven tracking — all of which affect compaction accuracy and can accelerate wear on surrounding components.
