Description

Full Technical Description

The BEARING 3128 3094 56 (also indicated as 3128309456 and 3128-3094-56) is a mining-grade precision bearing engineered for EPIROC and ATLAS COPCO drilling rigs, ROC-series machinery, and underground jumbos. The BEARING 3128 3094 56 ensures smooth rotational motion for shafts, gears, feed mechanisms, and drifter assemblies subjected to vibration, radial forces, axial forces, and continuous drilling stress.

This BEARING 3128 3094 56 is manufactured from hardened bearing steel with precision-ground raceways and optimized internal geometry for low friction, long service life, and high load endurance even under hydraulic-oil exposure, abrasive dust, and heavy drilling impacts. OEM numbers 3128309456 and 3128-3094-56 confirm OEM-level compatibility.

Function & Operation

The BEARING 3128 3094 56 stabilizes rotating components within drifters, feed drives, hydraulic motors, and gearbox assemblies. Proper bearing function improves drilling accuracy, reduces heat buildup, and extends the lifespan of surrounding components in mining and tunneling applications.

Reliability & Maintenance

Inspect the BEARING 3128 3094 56 for corrosion, pitting, lubrication loss, abnormal noise, or increased play. Replace 3128 3094 56 immediately if vibration or rotational instability develops.
