Mining & Construction: Heavy-Duty Performance

Mining operations require equipment that can run 24/7 in high-pressure, abrasive, and vibration-heavy environments. UMZ Bearing provides heavy-duty tapered roller bearings specifically designed to minimize downtime and maximize productivity in the earthmoving and mineral processing sectors.

Powering the Toughest Machinery

Our high-load capacity bearings are the backbone of critical mining equipment:

• Crushers & Screeners: Mining crushers face massive shock loads and constant vibration. Our bearings are manufactured with reinforced cages and high-purity steel to maintain structural integrity under extreme pressure.

• Conveyor Systems: For the long-distance transport of ore and minerals, our bearings ensure low-friction rotation for conveyor pulleys and idlers, reducing energy consumption and preventing costly belt failures.

• Large Off-Highway Trucks: We support the massive wheel ends and final drives of haul trucks. These bearings are precision-engineered to carry hundreds of tons while navigating uneven, rocky terrain.

• Excavators & Drills: From the swing gears to the crawler drives, UMZ bearings provide the stability and torque resistance necessary for heavy excavation and deep-hole drilling.

Engineering for Extremes

To thrive in the mining sector, UMZ bearings are built with:

1. High-Purity GCr15 Steel: Advanced metallurgical standards ensure resistance to subsurface fatigue and crack propagation.

2. Specialized Heat Treatment: Our bearings undergo precise tempering to achieve the ideal balance of surface hardness and core toughness, allowing them to absorb heavy impacts without shattering.

3. Contamination Control: Available with heavy-duty labyrinth seals and specialized grease-retention features to keep abrasive ore dust out of the rolling elements.
