Rolling bearings significantly contribute to technological advancements in mining and raw material processing. The harsh operating and environmental conditions demand exceptionally robust bearings, such as so-called vibrating screen bearings. These are special spherical roller bearings that, due to their high robustness, can compensate for shock loads, misalignment, and severe vibrations.
The uniform and sufficient grease/oil supply to both rows of rollers is usually ensured by lubrication through a lubrication groove or lubrication holes in the outer ring.
