A rubber bearing with a bearing body implemented as an elastomer spring, wherein the spring travel of the bearing body is limited in at least one damping direction by path delimiters. The path delimiter(s) are formed by at least two corresponding stop elements, whereby the spring travel of the elastomer bearing body in the respective direction is determined by the spacing or gap between the stop faces of the stop elements which form the path delimiter. The rubber bearing is constructed so that it can adapt to changing preloads. The path delimiter is designed so that the position of one of its stop elements can be changed, the spacing between the stop face of this stop element and that of the corresponding stop element can be changed, and the new position of the corresponding stop element can be fixed again. The position of the stop element is changed by an actuator arranged on the bearing or by temporarily loosening a locking means and passively tracking the position of the stop element according to the preload.

A hydraulically damping rubber mount is provided with a variable channel length. The mount channel length can be adapted to the later intended use with a simple design during the manufacture without changing the design. The hydraulic mount has an elastomeric damping member, at least two chambers to accommodate a fluid damping agent and a channel carrier with a channel connecting the chambers in a flow-conducting manner. The channel has passage openings to the chambers. An incompletely closed ring, one end of which forms a channel deflection, is displaceably guided in the channel in the manner according to the present invention. The channel is divided as a result into two channel parts, which unite between the ends of the ring and through which the damping agent flows in opposite directions.
