The invention relates to a method for producing a bush body (14), in particular from a ceramic material, wherein the bush body (14) has an opening (12) and an outer surface (18). The bush body (14) is made from ceramic material in the form of a tube (32). For wall thickness to height ratio of ca. = 1 : 4 to 1 : 5, the bush body (14) is produced by extrusion, for a wall thickness to height ratio of ca. = 1 : 4 to 1 : 5 the bush body (14) is produced by dry pressing. The outer surface (18) is provided with a positive profiling (30, 42, 44, 48, 78, 88, 98) or a roughening (48, 62) or a negative profiling (52). For long bushes isostatic presses are preferably also used. |
