The Bomag 05521930 Supporting Disc is a genuine OEM replacement component designed for a broad range of Bomag single drum rollers, walk-behind rollers, pneumatic tyred rollers, and recycler/stabilizer equipment. Sourced directly from Bomag, this supporting disc meets the same standards as the original part installed at the factory. Confirmed fitment spans the BW 200-series single drum roller lineup — including BW 211, BW 212, BW 213, BW 214, BW 216, BW 219, and BW 226 variants — along with BW 60 S and BW 75 S-2 walk-behind rollers, BW 24 RH, BW 25 RH, BW 27 RH, and BW 28 RH pneumatic tyred rollers, the C 850 C single drum roller, and the BSF 2500 recycler/stabilizer. If you're working with Bomag part number 05521930, this is the verified OEM disc for your machine.
Key Features
- Genuine OEM Construction — Manufactured to Bomag's original material and dimensional specifications, ensuring this supporting disc delivers the same structural integrity as the part it replaces.
- Broad BW-Series Coverage — Fits a wide range of Bomag single drum rollers including BW 211, BW 213, BW 216, BW 219, and BW 226 series, plus BW 60 S and BW 75 S-2 walk-behind rollers, BW 24 RH, BW 25 RH, BW 27 RH, and BW 28 RH pneumatic tyred rollers, and the BSF 2500 recycler/stabilizer.
- Direct Drop-In Replacement — Engineered to match the original mounting dimensions and interface, allowing this disc to install into the existing assembly without modification or adaptation to surrounding components.
- Structural Support Where It Counts — A worn or cracked supporting disc compromises the load path within the drum or drivetrain assembly; replacing it restores proper load distribution and protects adjacent components from premature wear.
A supporting disc is a structural interface component that transfers and distributes mechanical loads between adjacent assemblies — typically within a drum, bearing housing, or drive arrangement. It acts as a precisely sized seat or backing surface, holding moving or fixed components in correct alignment under the high cyclic loads that compaction equipment generates. When a supporting disc wears, cracks, or loses its geometry, the components it supports can shift, causing accelerated wear on bearings, seals, and housings. Replacing this disc with a correctly dimensioned OEM part restores the designed load path and keeps the surrounding assembly operating within its intended tolerances.
