A bearing arrangement having a roller bearing ( 3; 4 ) having an inner race ( 5; 8 ), bearing rollers ( 6; 9 ) and an outer race ( 7; 10 ) in which the roller bearing ( 3; 4 ) is arranged to support a wheel hub ( 2 ) on a wheel axle ( 1 ). The bearing arrangement further includes a first seal ( 17, 22 ) and a second seal ( 19, 24 ) which have been arranged on either side of the bearing rollers ( 6, 9 ), wherein closed bearing spaces ( 18, 21; 23; 26 ) are delimited between the first seal ( 17, 22 ) and the bearing rollers ( 6; 9 ), and between the second seal ( 19; 24 ) and the bearing rollers ( 6; 9 ), respectively. The invention facilitates an improved arrangement in the form of a combined bearing and sealing device that is assembled in advance to allow simple mounting on a wheel axle.
