The Bomag 05520112 is a genuine OEM Supporting Disc designed for a broad range of Bomag tandem rollers and vibratory plates. Sourced directly from Bomag, this component meets the original design and dimensional requirements for the machines it serves. This supporting disc fits tandem roller models including the BW 80 AD-2, BW 90 AD-2, BW 100 AD-3, BW 100 AD-4, BW 120 AD-3, BW 120 AD-4, BW 125 AD-4, BW 125 ADH, BW 135 AD, BW 138 AD, BW 141 AD-2, BW 144 AD-2, BW 151 AC-2, BW 151 AD-2, BW 154 AD-2, BW 170 AD, BW 174 AC, BW 174 AD, BW 184 AD, BW 213 D, and additional variants across the BW tandem roller range, as well as BP vibratory plate models including the BP 20/48, BP 20/53, BP 23/48, BP 23/48 D, BP 23/60, and BP 23/60 D. When you need a direct replacement backed by Bomag's own engineering, part number 05520112 is the correct choice.
Key Features
- Genuine OEM Dimensional Accuracy — manufactured to Bomag's original tolerances, ensuring the supporting disc seats and functions exactly as the original component was engineered to do
- Direct Drop-In Replacement — matches the original mounting configuration on both BW tandem rollers and BP vibratory plates, slotting into place without alteration
- Wide Fitment Coverage — compatible with an extensive range of Bomag equipment, including BW tandem rollers from the BW 80 AD-2 through to the BW 213 D, and BP forward vibratory plates including the BP 20/48, BP 23/48 D, BP 23/60, and BP 23/60 D
- Structural Integrity Under Load — a correctly functioning supporting disc maintains proper component alignment and load distribution; a worn or damaged disc can lead to misalignment, accelerated wear on adjacent components, and degraded compaction performance
- Verified Bomag Part Number — order with confidence using part number 05520112, the exact Bomag catalog reference for this supporting disc across all listed machines
The supporting disc is a structural component that provides a stable bearing surface or mounting foundation for rotating or load-bearing assemblies within the machine's drivetrain or vibration system. It distributes axial and radial forces evenly, preventing localized stress concentrations that can damage housings, shafts, or adjacent components. When a supporting disc wears, deforms, or fractures, the assemblies it supports lose proper alignment, which can cause increased vibration, abnormal noise, and progressive damage to surrounding parts — making timely replacement essential to keeping the machine operating correctly.
