In the mining sector severe operating and environmental conditions require extremely robust bearings. Bearings for mining industry are used for bucket wheel excavators, draglines, conveyor belts, trucks, stackers, transport equipment, loaders, longwall shearers and hoists. The mining industries use many types of bearings: roller bearings, deep groove ball bearings, spherical roller bearings and tapered roller bearings.
DEEP GROOVE BALL BEARINGS
The mining industries use belt conveyors for transporting bulk materials. The conveyors run on idlers and a lot of them extend over many kilometers; thus the number of idlers needed may be very large. The deep groove bearings (design 2ZR and 2RS) are sealed by dust shields and seals on both sides, and filled with grease for a long service life.
SPHERICAL ROLLER BEARINGS
In the mining sector severe operating and environmental conditions require extremely robust bearings. Mining machinery faces some of the toughest terrains and operating conditions of any industry. Heavy loads, debris, severe misalignment and wide variances in speeds are some of the challenges faced by bearings in the excavating, loading, hauling and processing equipment.
