BEARING
BEARING 3128 3170 11 This is the material found inside the rock drilling bit. It is made of bronze. It is placed on the damping piston like a ring. It serves as a bearing between the middle body of the drill and the damping piston. Therefore, the 3128317011 Bearing prevents damage to the main part. It helps the drill operate longer.

Full Technical Description
The BEARING 3128 3170 11 (also indicated as 3128317011 and 3128-3170-11) is a mining-grade precision bearing engineered for EPIROC and ATLAS COPCO drilling rigs, ROC-series machinery, and underground jumbos. The BEARING 3128 3170 11 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 3170 11 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 3128317011 and 3128-3170-11 confirm OEM-level compatibility.
Function & Operation
The BEARING 3128 3170 11 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 3170 11 for corrosion, pitting, lubrication loss, abnormal noise, or increased play. Replace 3128 3170 11 immediately if vibration or rotational instability develops.
