The GEG..ES Series extra-large spherical plain bearings handle massive loads in heavy industrial applications. The oversized steel-on-steel design with lubrication grooves and multiple lube holes ensures proper grease distribution across the large sliding surfaces. These bearings are engineered for extreme-duty oscillating applications where standard spherical plain bearings are insufficient. Used in steel mill continuous casting oscillators, dam gate trunnion bearings, ship loader boom pivots, and bridge structural expansion bearings.
