An elastic rubber bearing is provided with an intermediate tube, namely, a bush bearing with a reinforcing insert arranged in the elastomeric bearing body. The design of the bearing includes a pretension, which is distributed as uniformly as possible both in relation to the circumference and in the axial direction. The pretension is generated in the elastomer in a bearing body after the vulcanization by calibrating the outer sleeve. A reinforcing element of the bearing includes an intermediate tube slotted on two sides in relation to its axial extension.
