ABSTRACT:
A sealed four-row tapered roller bearing, useable for working rolls of roll stands, is provided with axial multipart inner and outer races and tapered rollers arranged between the bearing races, sealing of the seat of the outer race parts in the housing being preferably effected by O-rings which are arranged in annular grooves of the outer race parts. The bearing chamber is sealed axially outward by sealing rings which are fastened in annular grooves in the bore of the outer race parts and rest with sealing lips on surfaces of the inner race, the separating line between the front faces of the inner races being sealed off by a sealing ring which rests on the inner races. The bearing chamber of the four-row tapered roller bearing is protected against the penetration of dirt and the tapered roller bearing can easily be assembled and disassembled as a result of the bore of the sealing ring being provided with continuous ribs which delimit at least one chamber for receiving lubricant, the sealing ring being arranged and centered on preferably cylindrical surfaces of inner race prolongations facing one another.
