The Bomag 05121077 Angular Ball Bearing is a genuine OEM component designed for Bomag BT 60, BT 65, BVT 65, BT 60 G, BT 65 G, BT 50, and BT 60 e tampers. Sourced directly from Bomag, this bearing meets the exact tolerancing and load specifications required for proper tamper operation. If your machine is showing signs of vibration irregularity, noise, or drive-train roughness, replacing this bearing with the correct part number 05121077 restores proper function and protects surrounding components from accelerated wear.
Key Features
- OEM Precision Tolerancing — manufactured to Bomag's exact angular contact geometry, ensuring correct axial and radial load handling under the high-cycle vibratory demands of tamper operation
- Direct Drop-In Replacement — engineered to the original dimensional spec so this angular ball bearing seats correctly without modification or shimming
- Broad Tamper Coverage — fits Bomag BT 50, BT 60, BT 60 e, BT 60 G, BT 65, BT 65 G, and BVT 65 tampers, covering a wide range of Bomag rammer models in the field
- Sustained Drive-Train Integrity — a worn angular ball bearing allows shaft deflection and heat buildup that damages housings and seals; replacing it at the correct service interval keeps drivetrain components running true
- Genuine Bomag OEM Part — supplied under part number 05121077 with full Bomag OEM lineage, so you receive the identical component installed at the factory rather than an approximation
An angular ball bearing is engineered to carry both radial and axial (thrust) loads simultaneously, making it the right choice for rotating shafts that experience combined forces — exactly the conditions inside a vibratory tamper's drive assembly. In a Bomag tamper, this bearing supports the crankshaft or exciter mechanism, allowing it to spin smoothly while absorbing the repetitive shock loads generated during compaction. When the bearing wears or fails, the shaft loses precise alignment, leading to increased vibration at the handles, unusual noise, overheating, and eventual damage to adjacent seals and housings.
