The Bomag 05520920 Supporting Disc is a genuine OEM component designed for a broad range of Bomag reversible vibratory plates, single drum rollers, tandem rollers, walk-behind rollers, recyclers/stabilizers, and cold milling machines — including the BPR 30/38 D, BPR 75/60 D-3, BW 213 DH-5, BW 145 PDH-5, BW 138 AD-5, MPH 122, MPH 600, RS 500, RS 650, BM 1000/35-2, and many more. Sourced directly from Bomag, this supporting disc meets the same specifications as the part originally installed at the factory. Verifying part number 05520920 against your machine's serial number and model code before ordering ensures a correct, direct-fit installation.
Key Features
- Genuine OEM Construction — manufactured by Bomag to the exact material grade and dimensional tolerances required for a structural disc application, ensuring consistent load distribution and long service life
- Wide Cross-Machine Compatibility — a single part number covers BPR reversible vibratory plates, BW single drum and tandem rollers, BW walk-behind rollers, MPH and RS recyclers/stabilizers, and BM cold milling machines, making it a versatile stocking item for mixed fleets
- Direct-Fit Replacement — matches the original mounting interface and disc geometry so this supporting disc installs without rework or shimming on every covered model
- Structural Integrity Under Vibration — a supporting disc bears and distributes mechanical loads in high-cycle vibratory environments; a worn or cracked disc can allow shaft or bearing misalignment that accelerates adjacent component wear
- Authentic Bomag Part — ordering by part number 05520920 through an authorized Bomag parts distributor confirms you receive the correct OEM disc, not a generic substitute with unknown material properties
A supporting disc acts as a load-bearing interface between rotating or vibrating assemblies, maintaining correct axial positioning and distributing clamping or thrust forces across the mating surfaces. In vibratory compaction equipment and heavy rollers, this disc is subject to continuous cyclic stress, making material quality and dimensional accuracy critical to its service life. When a supporting disc wears, cracks, or loses its geometry, the components it supports — such as bearings, shafts, or drive elements — can shift out of alignment, causing accelerated wear, vibration anomalies, and potential damage to surrounding assemblies.
