The Bomag 05121006 Angular Ball Bearing is a genuine OEM component designed for BW 65 HS, BW 65 S, and BW 65 S-2 walk-behind light rollers. Sourced directly from Bomag, this bearing meets the original design tolerances required to maintain smooth, stable drum rotation under compaction loads. It fits directly into the bearing seat without modification, making it the straightforward choice for service and rebuild work on these machines.
Key Features
- OEM-Grade Angular Contact Precision — manufactured to Bomag's original bearing geometry, ensuring correct load distribution across both radial and axial forces during drum operation
- Direct-Fit Replacement — dimensionally identical to the original, this bearing seats correctly in the BW 65 series bearing housing for a clean, straightforward installation
- Confirmed Fitment — genuine OEM coverage for BW 65 HS, BW 65 S, and BW 65 S-2 walk-behind light rollers
- Sustained Drum Performance — a properly functioning angular ball bearing keeps the drum spinning true and absorbs combined loads; a worn bearing leads to vibration, uneven wear, and premature drivetrain damage
- Genuine Bomag Part — supplied as an authentic OEM component under part number 05121006, eliminating guesswork on specification and sourcing
An angular ball bearing is engineered to handle both radial loads and axial (thrust) loads simultaneously, making it well suited to rotating assemblies that experience force from multiple directions — such as a compactor drum shaft. By maintaining precise alignment between rotating and stationary components, the bearing allows the drum to spin smoothly and efficiently under the stresses of vibratory compaction. When this bearing wears or fails, operators typically notice increased vibration, noise at the drum, or uneven compaction output — all signs that the bearing is no longer holding correct alignment and needs immediate replacement.
