A double row bearing assembly (10, 20, 30, 40 50) comprising a first portion (2) and a second portion (3) is described. The first portion (2) comprises a first ring (4) and a second ring (5). The first ring (4) is connected with the second portion (3) by means of at least one row of tapered rollers (6) or at least one row of balls and the second ring (5) is connected with the second portion (3) by means of at least one row of tapered rollers (7) or at least one row of balls. The bearing assembly (10, 20, 30, 40 50) comprises at least one spacing means (8, 18, 28, 29, 38, 48) which is located between the first ring (4) and the second ring (5). The contact surfaces (17, 25, 26, 27,36, 37, 47) between the spacing means (8, 18, 28, 29, 38, 48) and the first ring (4) and between the spacing means (8, 18, 28, 29, 38, 48) and the second ring (5) have a higher frictional coefficient than a direct contact surface between the first ring (4) and the second ring (5). |
