ABSTRACT:
A slide bearing has a bearing bore for accommodating a shaft acted upon at least temporarily by a radial force. At least one bearing end of the slide bearing has at least one chamfer for preventing a contact between the shaft and the slide bearing and/or for facilitating the supply of the slide bearing with lubricating medium. In a preferred embodiment, in which the radial force acts essentially in a predetermined direction onto the shaft, at least one chamfer is provided on an unstressed side created because of the predetermined force effect, which chamfer is larger than a chamfer on a stressed side situated opposite the unstressed side. By means of the chamfer or chamfers, the danger of contact on the unstressed side caused by a bending of the shaft is reduced and the supply of the slide bearing with lubricating medium is increased without significantly reducing the bearing length on the stressed side which essentially carries the bearing load.
