The Bomag 05121005 Angular Ball Bearing is a genuine OEM component designed for Bomag BT 50, BT 60, and BT 60 G tampers, as well as BW 219 D-4i, BW 219 DH-4i, BW 219 PDH-4i, BW 226, and BW 226 DH-4i single drum rollers. Sourced directly from Bomag, this bearing is manufactured to the same tolerancing and load specifications as the original, ensuring proper fit within the machine's drivetrain or vibration assembly. Confirmed fitment also covers the BT 60 e tamper and EU-Flex variants of the BW 219 DH-4i and BW 226 DH-4i, making part number 05121005 a precise match across a broad range of Bomag equipment.
Key Features
- OEM Angular Contact Precision — manufactured to Bomag's exact radial and axial load tolerances, ensuring the bearing handles combined loading forces the way the original design demands
- Direct-Fit Replacement — dimensionally identical to the factory bearing, this component seats and retains correctly without rework or shimming
- Broad Confirmed Fitment — fits BT 50, BT 60, BT 60 G, and BT 60 e tampers, plus BW 219 D-4i, BW 219 DH-4i, BW 219 PDH-4i, BW 219 DH-4i EU-Flex, BW 226, BW 226 DH-4i, and BW 226 DH-4i EU-Flex single drum rollers
- Sustained Load Capacity — angular ball bearings support simultaneous radial and thrust loads; a worn or failed bearing causes vibration, heat buildup, and premature wear on surrounding shaft and housing components
- Genuine Bomag OEM Part — supplied under part number 05121005, this bearing carries the same quality assurance as components installed at the factory, with no uncertainty about sourcing or specification
An angular ball bearing is engineered to carry both radial loads and axial (thrust) loads simultaneously, thanks to the angled contact geometry between its balls and raceways. In Bomag tampers and single drum rollers, these bearings are commonly found in drive shafts, vibration mechanisms, and eccentric assemblies where combined loading is constant and precise rotational support is critical. When an angular ball bearing wears or fails, the result is increased heat, audible noise, shaft play, and eventual damage to adjacent components — making timely replacement with a correctly specified part essential to keeping the machine operating within its designed performance envelope.
