Abstract: A bearing arrangement is equipped with a radial bearing and with a roller bearing which acts purely in the axial direction. Rollers of axial bearing have a needle-like, barrel-like design. Bearing rings are provided with the corresponding profiles. When axial play develops in the bearing arrangement, rollers shift radially under the effect of gravity in one case and under the effect of centrifugal force in the other with the effect of eliminating the axial play.

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.
