The Bomag 05114077 Grooved Ball Bearing is a genuine OEM component designed for Bomag BT-series tampers, including the BT 50, BT 55, BT 58, BT 60, BT 60/4, BT 65, BT 65/4, BT 68, BT 70, BT 75, BT 80 D, BT 80 D - Torso, and BT 50 Typ2. Sourced directly from Bomag, this bearing meets the exact dimensional and load tolerances specified for these machines. Correct bearing fitment is critical on tamping equipment, where high-cycle vibration places constant stress on rotating components — installing the right OEM part keeps that stress within designed limits. Confirm your model against part number 05114077 before ordering to ensure a direct, compatible replacement.
Key Features
- OEM Precision Tolerancing — manufactured to Bomag's exact radial clearance and load-rating specifications, ensuring the bearing handles the high-frequency vibration cycles generated by BT-series tampers without premature fatigue.
- Direct Drop-In Replacement — matches the original bearing's bore, outer diameter, and width so it seats correctly in the housing without modification to the surrounding assembly.
- Broad BT-Series Coverage — fits the BT 50, BT 50 Typ2, BT 55, BT 58, BT 60, BT 60/4, BT 65, BT 65/4, BT 68, BT 70, BT 75, BT 80 D, and BT 80 D - Torso tampers, making it a versatile stocking part for fleets running multiple BT models.
- Sustained Rotation Under Load — a properly functioning grooved ball bearing maintains smooth, low-friction rotation in the drive mechanism; a worn or failed bearing causes vibration loss, overheating, and accelerated wear on adjacent components.
- Genuine Bomag OEM Part — supplied as an authentic Bomag component under part number 05114077, giving you confidence that the specification, material grade, and quality control match what was installed at the factory.
A grooved ball bearing — also known as a deep-groove ball bearing — supports both radial and moderate axial loads while allowing a shaft to rotate freely within its housing. In a Bomag tamper, bearings like this one are found in the drive and exciter assemblies, where they must endure the intense, repetitive impact forces produced during compaction. When a bearing wears out, it generates heat and noise, reduces compaction efficiency, and can ultimately seize, causing collateral damage to the shaft or housing around it — making timely replacement with the correct OEM part essential to keeping the tamper performing as intended.
