The Bomag 46280105 Oscillating Articulated Joint Assembly is a genuine OEM component designed for Bomag BW 80 AD-5, BW 90 AD-5, BW 90 SC-5 series tandem rollers and the BW 900-50 walk-behind roller. Sourced directly from Bomag, this assembly meets the exact tolerances and material specifications of the original installation, ensuring the articulation and oscillation system performs as the machine demands. This joint assembly fits the BW 100 SCC-5, BW 100 ADM-5, BW 100 SC-5, and BW 100 ACM-5 tandem rollers as well, making it a broad-coverage OEM solution across the compaction lineup. When the original joint wears or fails, replacing it with part number 46280105 restores the steering response and drum movement the machine was engineered to deliver.
Key Features
- OEM-Matched Joint Geometry — manufactured to Bomag's exact pivot dimensions and material grade, so the assembly transfers articulation forces without play or binding at the joint interface
- Drop-In Assembly — supplied as a complete assembled unit that aligns directly with the original mounting points on compatible Bomag tandem and walk-behind rollers
- Wide Model Coverage — fits BW 80 AD-5, BW 90 AD-5, BW 90 SC-5, BW 100 ADM-5, BW 100 SC-5, BW 100 ACM-5, BW 100 SCC-5 tandem rollers, and the BW 900-50 walk-behind roller
- Smooth Steering and Drum Oscillation — a correctly functioning joint keeps the front and rear frames articulating freely while allowing the drum to oscillate over uneven surfaces, maintaining consistent compaction contact
- Genuine Bomag Part — authentic OEM construction backed by Bomag's manufacturing standards, providing the same service life expected from the original component
The oscillating articulated joint assembly connects the front and rear frames of the roller while simultaneously allowing the drum axle to oscillate — moving independently up or down to follow grade changes. Articulation steers the machine through curves; oscillation keeps the drum in full contact with the surface regardless of minor undulations beneath it, which is critical for achieving uniform compaction density across the pass. When this joint wears, develops play, or seizes, operators will notice imprecise steering, uneven drum contact, and accelerated wear on surrounding frame and drive components — all of which compromise compaction quality and can lead to more extensive structural repairs if left unaddressed.
