Slewing bearings are integral to the efficient operation of stacker reclaimers, enabling the smooth movement and transportation of materials. These machines are divided into three sections: upper, middle, and lower, each utilizing slewing bearings to manage different forces, including axial and radial loads, as well as overturning moments.
Common types of slewing bearings in these applications include three-row cylindrical roller bearings, four-point contact ball bearings, and crossed cylindrical roller bearings. Many of these bearings are custom-designed to meet specific operational requirements, ensuring optimal performance under varying conditions.
