ANGULAR BALL BEARING

The 872 415 49 ANGULAR BALL BEARING (87241549, 872-415-49, ANGULAR BALL BEARING 87241549) is a mining-duty precision bearing engineered for Sandvik drilling rigs, ROC series machinery, and underground jumbos. The 872 415 49 ANGULAR BALL BEARING provides high-accuracy rotational support for shafts, gears, and mechanical assemblies exposed to extreme vibration, radial load, axial load, and continuous drilling forces.

This 872 415 49 ANGULAR BALL BEARING is made from hardened bearing steel with optimized raceway geometry, precision-ground balls, and low-friction lubrication channels to ensure maximum load capacity and long service life. OEM identifiers 87241549 and 872-415-49 guarantee compatibility across Sandvik parts systems.

The 872 415 49 ANGULAR BALL BEARING minimizes rotational resistance, stabilizes shaft alignment, reduces heat generation, and supports efficient energy transfer in drifter systems, hydraulic motors, gear drives, and feed mechanisms. Proper bearing performance improves drilling accuracy, reduces mechanical noise, and extends equipment lifespan in mining and tunneling environments.

Inspect the 872 415 49 ANGULAR BALL BEARING for pitting, corrosion, lubrication loss, abnormal noise, or excessive play. Replace 872 415 49 immediately if vibration increases or rotational smoothness declines.
