Description

Full Technical Description

The BEARING 5740 0079 52 (also indicated as 5740007952 and 5740-0079-52) is a mining-grade precision bearing engineered for EPIROC and ATLAS COPCO drilling rigs, ROC-series machinery, and underground jumbos. The BEARING 5740 0079 52 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 5740 0079 52 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 5740007952 and 5740-0079-52 confirm OEM-level compatibility.

Function & Operation

The BEARING 5740 0079 52 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 5740 0079 52 for corrosion, pitting, lubrication loss, abnormal noise, or increased play. Replace 5740 0079 52 immediately if vibration or rotational instability develops.
