In open pit mines all over the world, coal, ores and oil sand are transported in large dump trucks. FAG supplies not only the wheel bearings for the electrically driven rear wheels but also for the complete gears.
The wheel bearing arrangement consists of two tapered roller bearings in O-arrangement. Some of these bearings have an outside diameter of more than one meter. The gears are fitted with cylindrical roller bearings and double-row tapered roller bearings. In some cases planetary gears are used whose planet wheels run in specially developed spherical roller bearings.
Belt conveyors in open pit mines move large quantities of material over long distances.
FAG supply special housings and spherical roller bearings for the driven belt pulleys.
FAG spherical roller bearings are designed to withstand the harshest operating conditions and permit compensation of misalignments and shaft deflections. Special cylindrical roller bearings are used for hub mounted non-driven pulleys.
