The Bomag 05231112 Taper Roller Bearing is a genuine OEM component designed for Bomag BW-series tandem rollers and walk-behind light rollers. Sourced directly from Bomag, this taper roller bearing meets the original design specifications for the machines it serves, ensuring a correct, confidence-inspiring installation every time. This bearing is confirmed to fit an extensive range of BW tandem rollers — including the BW 100, BW 115, BW 120, BW 124, BW 125, BW 131, BW 135, and BW 138 series — as well as BW 75 S and BW 90 S walk-behind light rollers. When you order part number 05231112 from DHS Equipment, you are getting the exact Bomag-authorized component, not a guess.
Key Features
- Genuine OEM Precision — manufactured to Bomag's original bearing tolerances, delivering the load-handling capacity and dimensional accuracy this application demands
- Direct-Fit Replacement — engineered to the same geometry as the original, so this taper roller bearing seats into the housing correctly without modification
- Broad BW-Series Coverage — fits a wide range of Bomag tandem rollers across multiple generations, including BW 100, BW 115, BW 120, BW 124, BW 125, BW 131, BW 135, and BW 138 variants, plus BW 75 S and BW 90 S walk-behind light rollers
- Sustained Drum and Drivetrain Performance — a correctly functioning taper roller bearing supports combined radial and axial loads, keeping drum rotation smooth and drivetrain components properly aligned; a worn bearing leads to vibration, uneven compaction, and accelerated wear on surrounding components
- Verified Part Number Integrity — order with confidence using Bomag part number 05231112, cross-referenced against the original Bomag parts catalog for accurate identification
A taper roller bearing is designed to handle both radial loads (forces perpendicular to the shaft) and axial thrust loads (forces along the shaft) simultaneously, making it well suited to the demanding rotational and lateral stresses found in roller drum assemblies and drivetrain hubs. In a Bomag roller, these bearings support the drum shaft and other rotating assemblies, keeping them running true under the significant compaction forces the machine generates. When a taper roller bearing wears or fails, operators typically notice increased vibration, unusual noise from the drum area, or uneven compaction results — all signs that the bearing should be inspected and replaced promptly to avoid further mechanical damage.
