Key Features
- Genuine OEM Construction — Manufactured to Bomag's original tolerances and material specifications, ensuring this supporting disc performs exactly as the factory-installed unit did.
- Broad BW Series Coverage — Fits an extensive range of Bomag BW single drum rollers, tandem rollers, and pneumatic tyred rollers, including BW 124, BW 145, BW 174, BW 177, BW 184, BW 203, BW 24 RH, BW 27 RH, BW 28 RH, and more across multiple generation variants.
- Direct Drop-In Replacement — Engineered to match the original mounting interface and dimensional profile, allowing installation in place of the worn or damaged disc without modification.
- Structural Integrity Under Load — The supporting disc maintains correct component positioning and load distribution within the drum or drivetrain assembly, preventing misalignment that leads to accelerated wear on surrounding parts.
- Verified Part Number Traceability — Cross-referenced against Bomag's OEM catalog under part number 05522130, giving you confidence the right part is on its way before it arrives on site.
A supporting disc is a precision-fitted structural component that maintains the correct positioning and alignment of adjacent rotating or mounted assemblies within the roller's drum or mechanical system. It acts as a load-bearing interface, distributing forces evenly and preventing unwanted movement between mating components. When a supporting disc becomes worn, cracked, or damaged, it can allow misalignment to develop, which places added stress on bearings, seals, and other nearby parts — ultimately affecting compaction performance and accelerating wear across the assembly.
