Sealed Ultra-Large Bearing

Schaeffler unveiled a sealed 241/1250 spherical roller bearing, reportedly a world’s first. Featuring an outside diameter of nearly 2 m, the ultra-large bearing was specifically designed for the highest-capacity high pressure grinding roll crushers. It is engineered to prevent the crushing materials from contaminating its internal components. The bearing’s rolling elements reportedly weigh 60 kg each. The outside diameter of the molded seal is 1.4 m. Metal shields with an optimized polymer seal house the bearings.
