Key Features
- Genuine OEM Construction — manufactured by Bomag to the same material and dimensional standards as the original scraper, ensuring consistent blade contact and drum coverage on tandem rollers
- Direct Drop-In Installation — mounts to the same attachment points as the original assembly with no cutting, drilling, or adaptation required
- Broad Tandem Roller Coverage — fits BW 120 AC-3, BW 120 AD-3, BW 120 AC-4, BW 120 AD-4, BW 125 AC-4, BW 125 AD-4, BW 125 ADH, and related BW 120 and BW 125 variants
- Drum Protection — a correctly functioning scraper keeps the drum surface clear of asphalt and debris buildup, protecting drum integrity and maintaining a clean compaction pass
- Complete Assembly — supplied as a fully assembled unit so there is nothing to pre-assemble before installation, reducing time spent during maintenance intervals
The scraper on a tandem roller is positioned close to the drum surface to continuously clear asphalt, aggregate, and material pickup from the drum as it rotates. Keeping the drum clean is essential for producing a consistent, smooth mat finish — material buildup on the drum transfers irregularities directly to the asphalt surface and can cause premature drum wear. When the scraper blade wears down or the assembly becomes damaged, buildup accelerates and mat quality deteriorates, making timely replacement of this component critical to maintaining paving and compaction performance.
