Bomag 05522530 Supporting Disc

The Bomag 05522530 Supporting Disc is a genuine OEM component designed for a wide range of Bomag refuse/landfill compactors, soil compactors, the BW 332 single drum roller, and the RS 500 recycler/stabilizer. Sourced directly from Bomag, this supporting disc matches the original specification and installs without modification into every machine it is built for. Confirmed fitment spans the BC 571 RB, BC 572 RB-2, BC 671 RB, BC 671 RS, BC 672 RB, BC 672 RB-2, BC 672 RB-3, BC 672 RB-4, BC 672 EB-2, BC 771 RB, BC 771 RS, BC 772 RB, BC 772 RB-2, BC 772 RB-3, BC 772 RB-4, BC 772 RS, BC 772 RS-2, BC 772 RS-3, BC 772 RS-4, BC 772 EB-2, BC 972 RB, BC 972 RB-2, BC 1172 RB, and BC 1172 RB-2, as well as the BW 332 and RS 500. Ordering by part number 05522530 ensures you receive the exact disc your machine requires, protecting your investment and keeping the driveline assembly performing as intended.

Key Features

• Genuine Bomag OEM Construction — manufactured to the same material grade and dimensional tolerances as the original disc, ensuring correct load distribution and surface contact under heavy compaction cycles.
• Direct-Fit Replacement — matches the original mounting interface exactly, allowing straightforward installation into the supporting assembly without machining or adapting mating components.
• Broad Fleet Coverage — a single part number 05522530 covers BC-series refuse/landfill compactors from the BC 571 RB through the BC 1172 RB-2, BC 672 EB-2 and BC 772 EB-2 soil compactors, the BW 332 single drum roller, and the RS 500 recycler/stabilizer, making it a versatile stock item for mixed Bomag fleets.
• Sustained Load-Bearing Performance — a correctly seated supporting disc maintains proper axial alignment and distributes operational forces evenly; a worn or failed disc can lead to accelerated wear on adjacent driveline and drum components.
• OEM Part Number Confidence — cross-referencing against Bomag part number 05522530 before ordering eliminates the risk of receiving a mismatched disc, a critical step given the range of BC-series generations this part spans.

A supporting disc sits within the driveline or drum assembly and acts as a load-bearing interface between rotating or reciprocating components. Its job is to spread axial and radial forces across a controlled surface area, preventing metal-to-metal contact that would accelerate wear on the surrounding hardware. When the disc wears thin, cracks, or loses its seating, neighboring bearings, shafts, and housings take on unintended stress, which can lead to misalignment, vibration, and eventual failure of costlier assembly components. Replacing a worn supporting disc promptly with a genuine OEM part restores proper load distribution and protects the integrity of the entire assembly.
