The Bomag 05521525 Supporting Disc is a genuine OEM component designed for a wide range of Bomag vibratory plates, tandem rollers, walk-behind rollers, and cold milling machines. As a direct OEM replacement, this supporting disc is manufactured to the same specifications as the original part, ensuring proper function across every machine it serves. Compatible models include the BW 55 E, BW 75 AD, and BW 120 AD walk-behind and tandem rollers, vibratory plates such as the BP 25/48 D, BPR 35/60 D, BPR 40/60 D, and BPR 25/50 D, and cold milling machines including the BM 500/15, BM 1000/35-2, BM1200/30-T3, and BM1300/30-T3. Using part number 05521525 confirms you are installing the correct factory-specified disc for your Bomag equipment.
Key Features
- Genuine OEM Construction — manufactured by Bomag to exact original tolerances, ensuring the disc seats and loads correctly within the assembly without improvisation or adjustment
- Direct Replacement Fit — installs in place of the original supporting disc with no reworking, matching the original mounting geometry and contact face dimensions
- Broad Bomag Compatibility — fits vibratory plates including BP and BPR series, walk-behind and tandem rollers across the BW 55, BW 75, BW 100, BW 115, and BW 120 families, and cold milling machines in the BM series
- Structural Support Integrity — a worn or damaged supporting disc can cause misalignment and uneven load distribution within the drivetrain or exciter assembly, leading to accelerated wear on surrounding components
- Verified Part Number Confidence — ordering by Bomag part number 05521525 eliminates guesswork and ensures the correct disc reaches your machine the first time
A supporting disc provides a stable, load-bearing contact surface within a rotating or oscillating assembly, keeping components correctly aligned and evenly distributing mechanical forces during operation. In compaction and milling equipment, this disc prevents metal-to-metal contact between moving parts, reducing wear on shafts, hubs, and housings. When the disc wears thin or cracks, it can allow components to shift under load, causing vibration, noise, and progressive damage to the surrounding assembly that compounds repair costs over time.
