Abstract

A four-row tapered roller bearing for working rolls of roll stands includes a plurality of axially arranged inner ring parts forming an inner ring, a plurality of axially arranged outer ring parts forming an outer ring, and four annular rows of tapered rolls positioned between the inner and outer ring parts. Each inner ring part has an inner extension with the inner extensions possessing end faces that are directly positioned against one another along a partition groove. The end face of at least one of the inner extensions is provided with a plurality of spaced apart and radially extending grooves in which is received lubricant to lubricate said end faces of the inner extensions. An annular sealing ring encircles the outer surfaces of the inner extensions of the inner ring parts and have a pair of inwardly directed ribs which engage the outer surface of the inner extensions to form between the ribs and the outer surfaces of the inner extensions a closed chamber which bridges the partition groove.
