1. A damper bearing, comprising: a damper bearing housing,a damping element based on at least one elastomer, the damping element being fitted into the damper bearing housing, the damping element comprising a basic body which has substantially the form of a hollow cylinder with an axis, an outer circumferential surface, an inner circumferential surface and, in the axial direction, two opposite end faces, andan insert being form-fitted connected with the damping element by fitting the insert into a recess in the inner circumferential surface,wherein at least one of the end faces of the damping element has a profile in which the thickness at the circumference decreases in the axial direction away from the basic body, and wherein the axial profile height of the end face increases from the inner circumferential surface towards the outer circumferential surface,wherein the thickness at the circumference of the damping element decreases to such an extent that the thickness at the circumference at the top of the end face corresponds to 0% to 50%, of the thickness at the circumference at the profile base, andwherein the elastomer of the damping element is a cellular polyisocyanate polyaddition product. 2. The damper bearing according to claim 1, wherein all peaks of the profile of the end face are located within an inward extent perpendicular to the outer circumferential surface of the basic body of the damping element of from 0% to 50%, relating to the thickness at the circumference at the profile base. 3. The damper bearing according to claim 1, wherein the decrease in the thickness at the circumference of the damping element takes place linearly. 4. The damper bearing according to claim 3, the angle of slope between the rising end face and the perpendicular to the axis of the damping element being from 15° to 60°. 5. The damper bearing according to claim 1, wherein the outer circumferential surface of the basic body of the damping element has at least one indentation, which extends at least partially over the entire circumference, the inward extent of the indentation perpendicularly to the outer circumferential surface is from 1% to 50% of the thickness at the circumference, wherein the remainder of the thickness at the circumference measured outwardly from the inner circumferential surface is not less than 4 mm. 6. The damping element according to claim 5, wherein the at least one indentation extends over the entire circumference of the outer circumferential surface, such that the outer region of the end surface forms a bending lip, the distance between the middle of the indentation and the highest profile height in the axial direction being from 0.2 cm to 1.5. 7. The damper bearing according to claim 1, wherein the basic body of the damping element has an annular cross-sectional area. 8. The damper bearing according to claim 1, wherein the outer diameter of the basic body of the damping element is from 3.5 cm to 8.5 cm, and the height of the damping element is from 1.5 cm to 5 cm. 9. The damper bearing according claim 1, wherein the outer circumferential surface of the basic body of the damping element has at least one elevation, the outward extent of which perpendicularly to the circumferential surface is from 0.5 mm to 8 mm. 10. The damper bearing according to claim 9, wherein the at least one elevation extends over the entire circumference of the outer circumferential surface. 11. The damper bearing according to claim 1, the two end faces of the damping element having a profile in which the thickness at the circumference decreases in the axial direction away from the basic body. 12. The damper bearing according to claim 11, the two end faces of the damping element having the same profile. 13. A method for producing damping elements for installation in a damper bearing according to claim 1 in which the individual damping elements are cut from a prefabricated elastomer tube by means of a cutting tool.
