Bearing assembly

The invention relates to a bearing assembly (A) providing a bearing (1) having a first ring (2) with a hole (22), two front edges (23, 24) and an outer cylindrical surface (21), and a second ring (3) having a hole (32), two front edges (33, 34) and an outer cylindrical surface (31), the first and second rings (2, 3) being relatively in relative rotation about a central axis (X1). At least one row of rolling elements is housed in a bearing chamber (8) formed between an outer cylindrical surface (31) of the second ring (3) and a hole (22) of the first ring (2). The assembly is configured to be mounted in a housing. The assembly also includes at least one envelope (10, 40) mounted on one of the rings (2, 3) of the bearing (1), such that a dimensional difference between the housing and the bearing (1) is compensated by the envelope (10, 40). 本发明涉及种轴承单元(A)，包括轴承(1)，所述轴承(1)包括第圈(2)和第二圈(3)，所述第圈(2)具有孔(22)、两个外边缘(23、24)和外圆柱面(21)，所述第二圈(3)具有孔(32)、两个外边缘(33、34)和外圆柱面(31)。所述第和第二圈(2、3)相对地绕中心轴线(X1)相对旋转。至少列滚动单元容纳在轴承腔(8)中，轴承腔(8)形成
