Bearing and a method for producing a bearing
The disclosure relates to a bearing, having an inner core, an outer cage which surrounds the inner core in a radial direction, and an elastomer body which resiliently connects the inner core and the outer cage together, wherein the outer cage has an inner stop projection, wherein the inner stop projection protrudes radially inwards from an inner circumferential face of the outer cage and has an inner stop face, wherein the inner core has an outer stop projection, wherein the outer stop projection protrudes radially outwards from an outer circumferential face of the inner core and has an outer stop face which faces the inner stop face, and wherein the inner stop face and the outer stop face overlap in an axial direction. The disclosure relates further to a method for producing a bearing.
