The Bomag 84030208 Thrust Disc is a genuine OEM component designed for Bomag BW 141 AD-2, BW 144 AD-2, BW 151 AC-2, BW 151 AD-2, BW 154 AD-2, and BW141AD 2 tandem rollers. Sourced directly from Bomag, this thrust disc matches the original specification for a drop-in fit with no guesswork on compatibility. As a genuine OEM part, it carries the same engineering tolerances as the component that left the factory, giving you confidence that the fit, load capacity, and service life align with what the machine demands. If your roller is showing irregular axial play or wear at the bearing interface, replacing this disc with part number 84030208 restores proper drivetrain alignment and thrust control.
Key Features
- Genuine OEM Load Tolerance — manufactured to Bomag's original axial load and hardness specifications, so the disc handles the cyclic thrust forces produced during tandem roller compaction without premature wear.
- Direct Replacement Fit — engineered to the same dimensional profile as the original, seating correctly against mating bearing and shaft surfaces without rework or shimming.
- Broad Tandem Roller Coverage — confirmed fitment across the BW 141 AD-2, BW 144 AD-2, BW 151 AC-2, BW 151 AD-2, BW 154 AD-2, and BW141AD 2 tandem roller lineup.
- Drivetrain Stability — a correctly seated thrust disc maintains precise axial positioning of rotating components, preventing side-load migration that leads to accelerated bearing failure and uneven drum performance.
- Verified Part Number — ordering by part number 84030208 eliminates substitution risk, ensuring the disc you receive is the exact Bomag-specified component for these machines.
A thrust disc is a hardened washer-style component positioned within a rotating assembly to absorb and control axial (end-to-end) forces acting on a shaft or bearing. In a tandem roller, drivetrain components generate significant thrust loads during operation, and the thrust disc acts as a sacrificial wear surface that keeps those forces from transferring to more expensive adjacent parts like bearings or housings. When a thrust disc wears thin or develops uneven contact surfaces, axial play increases, leading to vibration, noise, and eventual damage to surrounding drivetrain components — making timely replacement essential to keeping the roller running true.
