The Bomag 31400445 Ball Bearing is a genuine OEM component designed for Bomag BW 212 D-3, BW 213 D-3, BW211D 3, BW 213 DH-3, BW 213 PDH-3, and BW 214 DH-3 single drum rollers. Sourced directly from Bomag, this ball bearing delivers the exact dimensional tolerances and load ratings required to keep these machines running at spec. Confirm part number 31400445 against your machine's serial plate before ordering to ensure a direct, accurate replacement.
Key Features
- Genuine OEM Precision — manufactured to Bomag's own tolerance specifications, ensuring the correct load rating, bore size, and race geometry for single drum roller drivetrains
- Direct Replacement Fit — drops into the same bearing seat as the original, with matching inner and outer diameters so installation follows the standard service procedure without modification
- Broad Single Drum Roller Coverage — confirmed fitment across the BW 212 D-3, BW 213 D-3, BW211D 3, BW 213 DH-3, BW 213 PDH-3, and BW 214 DH-3
- Sustained Load Capacity — a correctly seated ball bearing keeps drum rotation smooth and absorbs both radial and axial forces; a worn bearing leads to vibration, misalignment, and accelerated wear on surrounding components
- Authentic Bomag Part — backed by Bomag's OEM supply chain, so the metallurgy, surface finish, and clearance class match the original bearing that left the factory
A ball bearing supports rotating shafts and drum assemblies by reducing friction between moving parts, allowing smooth, controlled rotation under load. In a single drum roller like the BW 213 series, bearings carry the significant radial forces generated during compaction passes while maintaining precise shaft alignment. When a bearing begins to fail — through wear, contamination, or fatigue — operators typically notice increased vibration, unusual noise, or heat buildup, all of which can quickly escalate into damage to the drum drive or surrounding housings if left unaddressed.
