The Bomag 05522030 Supporting Disc is a genuine OEM component designed for the BW 142 D-2 single drum roller and BM-series cold milling machines including the BM 1000/35, BM 1200/35, BM 1300/35, BM 1200/35 T4f, BM 1300/35 T4f, BM 1000/35-2, BM1200/35-2, and BM1000/35-2. Sourced directly from Bomag, this supporting disc is manufactured to the same standards as the original part installed at the factory. Verified against Bomag's parts catalog using part number 05522030, this component delivers a direct, confident fitment across a broad range of Bomag equipment. When it comes to structural support components, exact fitment is critical — this genuine OEM part removes all guesswork.
Key Features
- Genuine OEM Construction — manufactured to original Bomag tolerances, ensuring the supporting disc seats and loads correctly within the assembly rather than approximating fit
- Direct Installation — matches the geometry and mounting interface of the original component, dropping in without modification or shimming
- Broad Equipment Coverage — fits the BW 142 D-2 single drum roller and the full BM 1000/35, BM 1200/35, and BM 1300/35 cold milling machine range, including T4f and dash-2 variants
- Structural Integrity Maintained — a worn or damaged supporting disc can allow unwanted movement in the assembly it backs, leading to accelerated wear on surrounding components and inconsistent machine operation
- Catalog-Verified Part Number — part number 05522030 is cross-referenced against Bomag's OEM parts catalog, so you can order with confidence knowing this is the correct disc for your machine
A supporting disc functions as a load-bearing backer within a rotating or reciprocating assembly, distributing axial or radial forces across a wider surface area to prevent concentrated stress on adjacent components. In heavy compaction and milling equipment, these discs help maintain proper alignment and preload within the assembly, protecting nearby bearings, housings, and drive elements from premature wear. When a supporting disc degrades or fails, the loss of even load distribution can cause vibration, accelerated component wear, and eventual damage to more costly surrounding parts.
