Bomag 05520620 Supporting Disc

The Bomag 05520620 Supporting Disc is a genuine OEM component designed for an exceptionally broad range of Bomag equipment, including tandem rollers, walk-behind and light rollers, single drum rollers, vibratory plates, reversible vibratory plates, trench compactors, cold milling machines, and recycler/stabilizer machines. As a direct OEM replacement sourced from Bomag, this supporting disc matches the original part in every critical dimension, ensuring a correct, trouble-free installation. Compatible machines span models including the BW 120 AD, BW 174 AD-2, BW 206 AD-5, BPR 75/60 D, BP 23/60 D, BW 55 E, BMP 8500, BM2000/65 Stage V, and RS460 STAGE V, among many others. Ordering by part number 05520620 confirms you are receiving the correct OEM disc for your specific machine.

Key Features

• Genuine OEM Dimensional Accuracy — manufactured to Bomag's original engineering tolerances, ensuring the disc seats and loads correctly within the assembly without adjustment
• Direct-Fit OEM Replacement — installs as a drop-in replacement for the original supporting disc, matching the mounting interface and thickness specifications of the factory component
• Exceptionally Wide Fitment Coverage — verified for use across Bomag tandem rollers, walk-behind and light rollers, single drum rollers, vibratory plates, reversible vibratory plates, trench compactors, cold milling machines, and recycler/stabilizer models including the BW 90 AD, BPR 50/52 D, BP 20/48, BW 124 DH-3, BW 141 AD-5, BMP 8500 Kubota, and BW 1050 T, among many more
• Structural Support for Critical Drive and Vibration Components — a correctly fitted supporting disc maintains proper load distribution and alignment within the assembly; a worn or missing disc can cause accelerated wear to adjacent components and lead to vibration imbalance or drive inefficiency
• Verified by Bomag Part Number — specifying part number 05520620 ensures an exact match to the OEM assembly, eliminating guesswork when sourcing across multiple machine models in a mixed fleet

The supporting disc functions as a load-bearing interface component within the assembly it is fitted to, distributing compressive or rotational forces evenly across mating surfaces to prevent localized wear and maintain correct component alignment. On compaction equipment, where vibration loads and operating stresses are high, this disc plays an essential role in protecting adjacent parts from premature failure. When the supporting disc wears thin or becomes damaged, uneven force distribution can cause accelerated deterioration of surrounding components, leading to increased operating noise, reduced compaction efficiency, and potential assembly failure if left unaddressed.
