The bucket wheel excavators operating at RWE Power in the Niederrhein region (Germany) are the biggest excavators in the world. FAG supply bearings both for the gear and for the bucket wheel shaft.

Split spherical roller bearings
Split spherical roller bearings are usually used to support bucket wheel shafts. This permits very cost-saving designs. Speedy bearing replacement cuts down on maintenance cost and drastically reduces downtimes.
Split cylindrical roller bearings
In many bucket wheel excavators the bearings supporting the gears for the bucket wheel drive are mounted directly on the bucket wheel shaft. Because of the attached flanges, only split cylindrical roller bearings can be mounted.
