The Bomag 05523035 Supporting Disc is a genuine OEM component designed for the BW 124 D single drum roller and a wide range of Bomag tandem rollers including the BW 120 AD, BW 125 ACH, BW 125 ADH, BW 131 AD-2, BW 131 AD-3, BW 131 AD-5, BW 131 ACW-2, BW 131 ACW-3, BW 131 ACW-5, BW 135 AC, BW 135 AD, BW 138 AC, BW 138 AD, and BW 138-AD. Sourced directly from Bomag, this supporting disc carries the same part number 05523035 used in the original build, so you can order with confidence that this is an exact match for your machine. This OEM part maintains the dimensional and material standards of the original, ensuring a correct installation without guesswork or modification.
Key Features
- Genuine OEM Construction — manufactured to the same dimensional and material tolerances as the original, delivering the structural rigidity and load distribution a supporting disc demands
- Exact-Match Replacement — identified by part number 05523035, this disc seats and aligns correctly within the drum or drive assembly, maintaining proper component spacing without shimming or rework
- Broad Roller Coverage — fits Bomag BW 124 D single drum rollers and fourteen tandem roller variants across the BW 120, BW 125, BW 131, BW 135, and BW 138 series, including ACH, ADH, ACW, AC, and AD configurations
- Sustained Compaction Performance — a correctly installed supporting disc keeps rotating and bearing components properly positioned, preventing uneven wear, vibration imbalance, and premature failure in demanding compaction cycles
- Direct OEM Source — supplied as a genuine Bomag part through DHS Equipment, ensuring the part you receive matches the original specification used on the production line
A supporting disc acts as a precision spacer and load-bearing interface within the drum or drivetrain assembly of a compaction roller. It maintains correct axial positioning between rotating components, distributing mechanical loads evenly and preventing metal-to-metal contact that would accelerate wear. When a supporting disc wears, cracks, or deforms, adjacent bearings and seals are exposed to misalignment and excess load — leading to accelerated component failure and loss of consistent drum operation during compaction work.
