Key Features
- Genuine OEM Construction — manufactured to Bomag's exact dimensional and material specifications for a supporting disc, ensuring correct load-bearing surface area and disc geometry on every installation
- Direct-Fit Replacement — engineered to drop into the original mounting position without rework, maintaining correct alignment with mating components
- Broad Roller Coverage — compatible with BW 55 E and BW 55 walk-behind / light rollers, and BW 80 AD-5, BW 90 AD, BW 90 AD-2, BW 90 AD-5, BW 100 ADM-5, BW 100 ACM-5, BW 135 AD-5, BW 138 AD-5, and BW 138 AC-5 tandem rollers
- Sustained Structural Support — a correctly functioning supporting disc keeps rotating or oscillating assemblies properly seated; a worn or missing disc allows lateral movement that accelerates wear on surrounding components
- Verified Part Number — order with confidence using Bomag part number 05520415, cross-referenced to the machines listed above for accurate fitment
A supporting disc serves as a precision locating and load-distributing element within the drum or drive assembly of a roller. It holds adjacent rotating components in their correct axial position, preventing unwanted movement that would otherwise generate heat, vibration, and premature wear on bearings and seals. When a supporting disc degrades or fails, operators may notice increased vibration, abnormal noise from the drum assembly, or accelerated wear on surrounding parts — all of which point to the need for prompt replacement to keep the roller performing as intended.
