At least one rolling bearing with rolling bodies may be arranged between the shaft and the at least one bearing point, the bearing having at least one rolling body cage configured to accommodate the rolling bodies and an outer ring. The rolling body cage may be fixed at least one of directly and indirectly to the shaft by a carrier ring and the outer ring may be fixed in the bearing point. The carrier ring may include the rolling body cage fixed thereon, the cage having a greater radial extent than the functional elements. The carrier ring may have a radial extent smaller than the greatest radial extent of one of the functional elements ## Claims ### Claim 1 A shaft arrangement comprising: a shaft with functional elements arranged thereon and at least one bearing point, wherein at least one rolling bearing with rolling bodies is arranged between the shaft and the at least one bearing point, the bearing having at least one rolling body cage configured to accommodate the rolling bodies and an outer ring, the rolling body cage fixed at least one of directly and indirectly to the shaft by a carrier ring and wherein the outer ring is fixed in the bearing point, the carrier ring including the rolling body cage fixed thereon, the cage having a greater radial extent than the functional elements, and the carrier ring having a radial extent smaller than the greatest radial extent of one of the functional elements. ### Claim 2 (depends on 1) The shaft arrangement according to claim 1, wherein the shaft is formed as a camshaft and the functional elements are formed as cams. ### Claim 3 (depends on 2) The shaft arrangement according to claim 2, wherein the shaft is formed as at least one of a built camshaft, as a forged camshaft, and as a cast camshaft. ### Claim 4 (depends on 1) The shaft arrangement according to claim 1, wherein the shaft is formed as a balance shaft and the functional elements are formed as balance weights. ### Claim 5 (depends on 1) The shaft arrangement according to claim 1, wherein the at least one bearing point is formed as a closed bearing block. ### Claim 6 (depends on 1) The shaft arrangement according to claim 1, wherein the outer ring is fixed in the bearing block by a thermal joint. ### Claim 7 (depends on 1) The shaft arrangement according to claim 1, wherein the carrier ring is at least one of: fixed on the shaft (2) by means of a thermal joint, formed integrally with the shaft, and wherein the rolling body cage is fixed to the carrier ring by fixing elements. ### Claim 8 (depends on 7) The shaft arrangement according to claim 7, wherein the fixing elements are at least one of: part of at least one of the carrier ring and the rolling body cage, formed as separate fixing rings which are at least one of compressed with the shaft and connected by means of a thermal joint, and formed as separate spacer rings configured to fix the rolling body cage to the carrier ring. ### Claim 9 (depends on 1) The shaft arrangement according to claim 1, wherein the rolling bodies are formed as at least one of needles, rollers and balls. ### Claim 10 (depends on 4) The shaft/bearing arrangement according to claim 4, wherein the rolling body cage is inserted into at least one of a groove in the carrier ring and the balance weight and thereby fixed. ### Claim 11 A bearing arrangement, comprising: a shaft with functional elements arranged thereon and at least one bearing point, wherein at least one rolling bearing with rolling bodies is arranged between the shaft and the at least one bearing point, the bearing having at least one rolling body cage configured to accommodate the rolling bodies and an outer ring, the rolling body cage fixed at least one of directly and indirectly to the shaft by a carrier ring and wherein the outer ring is fixed in the bearing point, the carrier ring including the rolling body cage fixed thereon, the cage having a greater radial extent than the functional elements, and the carrier ring having a radial extent smaller than the greatest radial extent of one of the functional elements. ### Claim 12 (depends on 11) The bearing arrangement according to claim 11, wherein the shaft is formed as a camshaft and the functional elements are formed as cams. ### Claim 13 (depends on 12) The bearing arrangement according to claim 12, wherein the shaft is formed as at least one of a built camshaft, as a forged camshaft, and as a cast camshaft. ### Claim 14 (depends on 11) The bearing arrangement according to claim 11, wherein the shaft is formed as a balance shaft and the functional elements are formed as balance weights. ### Claim 15 (depends on 14) The bearing arrangement according to claim 14, wherein the rolling body cage is inserted into at least one of a groove in the carrier ring and the balance weight and thereby fixed. ### Claim 16 (depends on 11) The bearing arrangement according to claim 11, wherein the bearing point is formed as a closed bearing block. ### Claim 17 (depends on 11) The bearing arrangement according to claim 11, wherein the outer ring is fixed in the at least one bearing point by a thermal joint. ### Claim 18 (depends on 11) The bearing arrangement according to claim 11, wherein the carrier ring is at least one of: fixed on the shaft by means of a thermal joint, and formed integrally with the shaft, and wherein the rolling body cage is fixed to the carrier ring by fixing elements. ### Claim 19 (depends on 18) The bearing arrangement according to claim 18, wherein the fixing elements are at least one of: part of at least one of the carrier ring and the rolling body cage, formed as separate fixing rings which are at least one of compressed with the shaft and connected by means of a thermal joint, and formed as separate spacer rings configured to fix the rolling body cage to the carrier ring. ### Claim 20 (depends on 11) The bearing arrangement according to claim 11, wherein the rolling bodies are formed as at least one of needles, rollers and balls.
