摘要

The bearing (1) has inner and outer sleeves (2, 3) rested against with each other radially by an intermediary of an annular support body (6) and an elastic annular amortization body (7). Two chambers (8, 9) are axially separated from each other between the sleeves. The support body includes channels (10) hydraulically connecting the chambers with each other. The channels are crossed through the support body and opened towards each chamber, where the channels are provided with a draft arranged between axial ends (11, 12) of the channels.
