Bearings Used in Mining Equipment
Mining machinery uses a wide range of bearing types depending on the equipment design and load conditions. The most common bearings used in mining applications include spherical roller bearings for crushers and vibrating screens, cylindrical roller bearings for conveyors and gearboxes, tapered roller bearings for transmissions, and slewing bearings for excavators and stacker reclaimers.
These bearings must provide high radial load capacity, resistance to shock loads, tolerance to shaft misalignment and reliable sealing against dust contamination.
Mining Bearings by Equipment Type
Crusher Bearings
Spherical roller bearings for jaw crushers, cone crushers and impact crushers. Designed to handle heavy radial loads and shock loads with excellent self-aligning capability.
