1. A sliding bearing (10) comprising a bearing body (11) which receives a shaft (1) in a guide bore (26), wherein the bearing body (11) is housed in a fixed element (2), wherein the bearing body (11) is provided on its outer circumference with a receptacle (14) in which is received an elastic bearin
1. A sliding bearing (10) comprising a bearing body (11) which receives a shaft (1) in a guide bore (26), wherein the bearing body (11) is housed in a fixed element (2), wherein the bearing body (11) is provided on its outer circumference with a receptacle (14) in which is received an elastic bearing element (12) bearing against the fixed element (2), wherein the receptacle has opposite sides spaced in a longitudinal direction of the bearing body, wherein guide ribs (16, 17) are arranged on both sides of the receptacle (14) on the outer circumference of the bearing body (11) and extend in the longitudinal direction of the bearing body (11) and form the receptacle (14) by way of mutually facing bevels (21, 22), and wherein the guide ribs (16) on one side of the receptacle (14) are angularly offset with respect to the guide ribs (17) on the other side of the receptacle. 2. The sliding bearing according to claim 1, characterized in that the receptacle (14) is a radially encircling, groove-shaped receptacle (14). 3. The sliding bearing according to claim 1, characterized in that the elastic bearing element (12) is a standardized component. 4. The sliding bearing according to claim 1, characterized in that the bearing body (11) consists of sintered metal, graphite, ceramic, plastic or hard metal. 5. A process for mounting shafts (1) in small electric motors (100), the process comprising using a sliding bearing (10) according to claim 1. 6. The process according to claim 5, comprising using the sliding bearing (10) in motor vehicle comfort drives. 7. The process according to claim 6, comprising using the sliding bearing (10) in power-window drives or seat adjustment drives. 8. The sliding bearing according to claim 1, characterized in that the fixed element is a housing. 9. The sliding bearing according to claim 1, characterized in that the elastic bearing element (12) is an O-ring or square ring. 10. The sliding bearing according to claim 1 wherein a distance in a circumferential direction between individual guide ribs is identical to a width in a circumferential direction of each guide rib. 11. The sliding bearing according to claim 10 wherein the bearing body has opposite ends spaced in the longitudinal direction, wherein the guide ribs on one side of the receptacle extend from one end of the bearing body to the receptacle, and wherein the guide ribs on the other side of the receptacle extend from the other end of the bearing body to the receptacle. 12. The sliding bearing according to claim 1 wherein the bearing body has opposite ends spaced in the longitudinal direction, wherein the guide ribs on one side of the receptacle extend from one end of the bearing body to the receptacle, and wherein the guide ribs on the other side of the receptacle extend from the other end of the bearing body to the receptacle. 13. A process for producing a sliding bearing (10) comprising a bearing body (11) which receives a shaft (1) in a guide bore (26), wherein the bearing body (11) is housed in a fixed element (2), wherein the bearing body (11) is provided on its outer circumference with a receptacle (14) in which is received an elastic bearing element (12) bearing against the fixed element (2), wherein the receptacle has opposite sides spaced in a longitudinal direction of the bearing body, wherein guide ribs (16, 17) are arranged on both sides of the receptacle (14) on the outer circumference of the bearing body (11) and extend in the longitudinal direction of the bearing body (11) and form the receptacle (14) by way of mutually facing bevels (21, 22), and wherein the guide ribs (16, 17) on one side of the receptacle (14) have an angle-of-rotation offset with respect to the guide ribs on the other side of the receptacle, characterized in that the bearing body (11) is produced by axial pressing by a tool (25), the process comprising, in order to form the guide bore (26), providing a first part of the tool (25) as a cylindrical mandrel (27), and moving toward the mandrel, from two different directions of a longitudinal axis (31) of the mandrel (27), parts of the tool including a bottom die (29) and a top die (28) in order, by means of pressure, to form the material into the bearing body (11). 14. The process according to claim 13, characterized in that the parts of the tool (25) serving as a bottom die (29) and top die (28) have a crown-like design. 15. The process according to claim 14, characterized in that tooth-like projections (30) of the crown-like bottom die (29) and top die (28) are moved toward one another to form the receptacle (14), wherein the projections (30) engage in one another over part of their length. 16. A process for producing a sliding bearing (10) comprising a bearing body (11) which receives a shaft (1) in a guide bore (26), wherein the bearing body (11) is housed in a fixed element (2), wherein the bearing body (11) is provided on its outer circumference with a receptacle (14) in which is received an elastic bearing element (12) bearing against the fixed element (2), wherein the receptacle has opposite sides spaced in a longitudinal direction of the bearing body, wherein guide ribs (16, 17) are arranged on both sides of the receptacle (14) on the outer circumference of the bearing body (11) and extend in the longitudinal direction of the bearing body (11) and form the receptacle (14) by way of mutually facing bevels (21, 22), and wherein the guide ribs (16, 17) on one side of the receptacle (14) have an angle-of-rotation offset with respect to the guide ribs on the other side of the receptacle, the process comprising fabricating the bearing body (11) by a noncutting production process.
