Frequently asked questions

Why are bearings critical in drilling equipment?

Bearings support rotating shafts and components under extreme loads and vibrations. Failed bearings can cause catastrophic damage to gearboxes, drive trains, and drilling mechanisms, leading to extended downtime and costly repairs.

What causes premature bearing failure in mining equipment?

Common causes include contamination from dust and water ingress, misalignment during installation, excessive loads, inadequate lubrication, and operating beyond rated temperature ranges. Proper sealing and regular lubrication schedules are essential preventive measures.
