Bearings are crucial in mining machinery, ensuring smooth operation under heavy loads and harsh conditions. They are used in equipment such as crushers, conveyors, and excavators to support rotating components like shafts, pulleys, and wheels. Bearings reduce friction, improve efficiency, and extend the life of machinery by minimizing wear. They also help maintain proper alignment and prevent overheating. Due to the demanding environment, high-performance bearings, such as roller bearings and spherical bearings, are often used to handle high loads and resist contamination.
