The Bomag 05520720 Supporting Disc is a genuine OEM component designed for a wide range of Bomag single drum rollers, tandem rollers, and reversible vibratory plates — including models BW 172 D-2, BW 124 D, BW 90 AD, BW 138 AD, BW 135 AD, BW 164 AD. Sourced directly from Bomag, this supporting disc meets the exact design and material standards of the original part it replaces. It delivers a direct, correct-fit installation on every compatible machine in the BW and BPR lineup covered by part number 05520720.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original material and dimensional specifications, ensuring the disc seats and functions exactly as the factory-installed component does in your roller or vibratory plate
- Broad Cross-Family Coverage — fits Bomag single drum rollers including the BW 172 D-2, BW 145 D-3, BW 177 D-3, BW 213 DH-3, BW 225 D-3, and BW 216 DH-3, as well as tandem rollers such as the BW 90 AD, BW 138 AD, BW 161 AD-4, BW 174 AD-2, and BW 203 AD-4, plus BPR reversible vibratory plates including the BPR 25/40 D, BPR 30/38 D, and BPR 50/55 D
- Structural Integrity Under Load — a correctly seated supporting disc maintains proper alignment and load distribution within the assembly; wear or failure can lead to excessive vibration, accelerated component wear, and loss of compaction efficiency
- Direct OEM Replacement — installs in place of the original disc without modification, using existing mounting points and hardware on all listed models
- Verified Part Number Fit — order with confidence using Bomag part number 05520720 to confirm you are receiving the correct disc for your specific machine variant
The supporting disc is a structural element within the drum or drive assembly of Bomag compaction equipment. It provides a stable bearing surface that distributes mechanical loads, keeps rotating or reciprocating components correctly aligned, and prevents metal-to-metal contact that would otherwise cause rapid wear. When a supporting disc becomes worn, cracked, or distorted, the surrounding components lose their alignment reference, which can result in increased vibration, uneven compaction output, and damage to adjacent parts — making timely replacement essential to keeping the machine performing to specification.
