Bearing arrangement with integrated electrical insulation, in particular for electric motor or machine

The device comprises a bearing (10) provided with a first ring (12) and a second ring (14) and at least one insulating sleeve (22) mounted on the second ring (14) of the bearing and provided with a seat (24) and an insulating liner (26) radially interposed between the second ring (14) and the seat (24) and made of an electrically insulating material. An insulating liner (26) is overmolded on the second ring (14) and the seat (24) of the bearing, the insulating liner (26) comprising two opposite end faces (26c, 26d) defining the insulating liner in the axial direction. An annular groove (32), an annular groove (34), is formed in each of the end faces (26c, 26d) and has a bottom (32a, 34a) that is axially offset toward the interior of the device with respect to an end face (14c, 14d) of the second ring and an end face (24c, 24d) of the seat located axially on one side of the end faces (26c, 26d). 装置包括轴承(10)和至少一个绝缘套筒(22)，轴承设置有第一圈(12)和第二圈(14)，至少一个绝缘套筒(22)安装在轴承的第二圈(14)上并设置有座(24)和绝缘衬里(26)，绝缘衬里(26)在径向上介于第二圈(14)与座(24
