The Bomag 05521730 Supporting Disc is a genuine OEM component designed for a wide range of Bomag BW series compaction equipment, including walk-behind light rollers, tandem rollers, single drum rollers, pneumatic tyred rollers, and trench compactors. As a direct OEM replacement, this supporting disc is manufactured to Bomag's original specifications, ensuring correct fitment across the full breadth of compatible machines. Confirmed fitment includes models such as the BW 75 ADL, BW 71 E, BW 120 AD, BW 174 AD, BW 177 D-4, BW 202 AD-5, BW 27 RH, and BW 1050 T, among many others in the BW lineup. Ordering by part number 05521730 guarantees you receive the correct component for your machine.
Key Features
- Genuine OEM Construction — Manufactured to Bomag's original design tolerances, ensuring the disc maintains correct load distribution and dimensional accuracy for this specific part type.
- Direct Drop-In Replacement — Engineered to match the original mounting configuration, allowing this supporting disc to install in place of the worn factory part without modification.
- Broad BW Series Coverage — Compatible with an extensive range of Bomag BW series machines, including walk-behind light rollers, tandem rollers, single drum rollers, pneumatic tyred rollers, and trench compactors such as the BW 850 T, BW 850 TR, BW 1050 T, and BW 650 T.
- Structural Support Integrity — A correctly functioning supporting disc keeps rotating or vibrating assemblies properly aligned and seated; a worn or damaged disc can lead to uneven load transfer, accelerated wear on adjacent components, and compromised compaction performance.
- Verified Bomag Part Number — Sourced directly from Bomag, part number 05521730 is traceable to the OEM catalog, giving you confidence you are installing the exact component your machine was built with.
The supporting disc serves as a foundational contact and load-bearing element within the drum or drive assembly, providing a stable interface that keeps rotating components correctly positioned during operation. Without a sound supporting disc, misalignment can develop between mating parts, increasing stress on seals, bearings, and surrounding hardware. Replacing a worn supporting disc restores proper contact geometry, protects adjacent components, and helps the machine maintain consistent compaction output across its working cycle.
