The Bomag 05231124 Taper Roller Bearing is a genuine OEM component designed for Bomag BW-series tandem rollers and the BW 124 D single drum roller. Sourced directly from Bomag, this taper roller bearing meets the original engineering specifications for the machines it serves — covering an extensive range including the BW 100 AC-3, BW 100 AD-3, BW 115 AC-3, BW 115 AD-3, BW 120 AD, BW 120 AD-3, BW 120 AD-4, BW 120 AC-4, BW 125 ADH, BW 131 AD-2, BW 131 AD-3, BW 131 AD-5, BW 135 AD, BW 138 AD, and more. When a bearing in this application wears or fails, correct load handling is compromised — replacing it with an authentic Bomag part number 05231124 keeps the drivetrain performing as engineered.
Key Features
- Genuine OEM Precision — Manufactured to Bomag's exact tolerancing specifications for correct radial and axial load distribution in tandem and single drum roller applications.
- Drop-In Replacement — Engineered to seat and preload exactly as the original, requiring no machining or shimming adjustments during installation.
- Broad BW-Series Coverage — Fits an extensive lineup of Bomag tandem rollers including BW 100, BW 115, BW 120, BW 125, BW 131, BW 135, and BW 138 series machines, as well as the BW 124 D single drum roller.
- Sustained Load Capacity — Taper roller bearing geometry handles combined radial and thrust loads efficiently, sustaining smooth drum and drivetrain rotation under the continuous stress of compaction work.
- Protects Adjacent Components — A correctly seated bearing prevents shaft movement and housing wear, reducing the risk of cascading damage to surrounding drivetrain components.
A taper roller bearing is engineered to carry both radial loads — forces perpendicular to the shaft — and axial (thrust) loads acting along the shaft. In Bomag tandem and single drum rollers, bearings in this position support drum shafts and drivetrain assemblies that are subject to constant vibration and compaction forces. When this bearing wears, it allows unwanted shaft play, which generates heat, accelerates housing wear, and can lead to drivetrain noise or failure. Replacing a worn bearing with the correct Bomag 05231124 restores proper preload and alignment, keeping drum rotation smooth and the compaction output consistent.
