The Bomag 88013015 Oscillating Articulated Joint Assembly is a genuine OEM component designed for Bomag BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 120 AD 4, BW 125 AD-4, and BW 125 AC-4 tandem rollers. Sourced directly from Bomag, this assembly meets the exact engineering specifications of the original part it replaces. This joint assembly installs directly into the articulation point of the machine frame, restoring the steering and oscillation geometry that these tandem rollers depend on for accurate tracking and drum contact across uneven asphalt surfaces. If you are servicing any of the BW 100, BW 120, or BW 125 series tandem rollers, part number 88013015 is the correct OEM replacement.
Key Features
- OEM-Grade Joint Integrity — manufactured to Bomag's original tolerances for articulation load and oscillation range, ensuring the joint performs exactly as the machine was engineered to operate
- Direct Assembly Replacement — supplied as a complete assembly that mounts to the existing frame pivot points on covered tandem rollers without modification to surrounding hardware
- Broad Tandem Roller Coverage — fits BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 120 AD 4, BW 125 AD-4, and BW 125 AC-4 tandem rollers, covering multiple AC and AD variants across three series
- Restored Steering Precision — a worn or damaged articulated joint causes steering slop, uneven drum alignment, and inconsistent compaction patterns; replacing it restores tight, predictable machine response
- Structural Safety Compliance — the articulated joint is a primary structural connection between the front and rear frames; using a genuine OEM assembly maintains the load ratings and safety margins Bomag specifies for these machines
The oscillating articulated joint assembly connects the front and rear frame sections of a tandem roller, allowing the machine to steer by articulating at its center and to oscillate so that both drums maintain ground contact over uneven surfaces. This dual function — articulation for steering and oscillation for ground-following — makes the joint one of the most mechanically demanding components on the machine. When the joint wears, play develops in the steering linkage, drums lose consistent contact with the mat, and compaction quality suffers; in severe cases, looseness in the joint can create unpredictable handling and accelerate wear on surrounding frame components. Replacing the assembly with a genuine Bomag part restores the tight tolerances the machine needs to track accurately and compact evenly on every pass.
