a bearing disposed in the housing wall; and a probe rotatably coupled to the housing, wherein the probe is capable of providing one or more dimensions of the pipe. ## Claims ### Claim 1 A measuring assembly for measuring one or more dimensions of a pipe that has an inner surface, and an outer surface, the measuring assembly comprising: a cylindrical housing capable of being disposed at least in part inside the pipe, the cylindrical housing having an inner housing space and a housing wall with an inner housing surface and an outer housing surface; a first bearing disposed in the housing wall; and a probe rotatably coupled to the housing, wherein the probe is capable of providing one or more dimensions of the pipe. ### Claim 2 (depends on 1) The measuring assembly of claim 1, wherein the first bearing is capable of being abutted against the cylinder. ### Claim 3 (depends on 1) The measuring assembly of claim 1, wherein the first bearing has a diameter greater than a thickness of the housing wall. ### Claim 4 (depends on 1) The measuring assembly of claim 1, wherein the first bearing is spherical. ### Claim 5 (depends on 1) The measuring assembly of claim 1, further comprising a second bearing extending through the outer housing surface. ### Claim 6 (depends on 1) The measuring assembly of claim 1, further comprising a second bearing and a third bearing, wherein the second bearing and the third bearing extend through the outer housing surface. ### Claim 7 A measuring assembly for measuring one or more dimensions of a pipe that has an inner surface, and an outer surface, the measuring assembly comprising: a cylindrical housing capable of being disposed at least in part inside the pipe, the cylindrical housing having an inner housing space; a sleeve disposed in the inner housing space; and a probe rotatably coupled to the housing, wherein the probe is capable of providing one or more dimensions of the pipe. ### Claim 8 (depends on 7) The measuring assembly of claim 7, wherein the sleeve has a tapered outer surface. ### Claim 9 (depends on 7) The measuring assembly of claim 7, wherein the sleeve has a frustoconical outer surface. ### Claim 10 (depends on 7) The measuring assembly of claim 7, wherein the sleeve has a plurality of portions including a narrow portion having a diameter less than any diameter of any other portion of the sleeve. ### Claim 11 (depends on 7) The measuring assembly of claim 7, wherein the sleeve includes a portion capable being abutted against a bearing. ### Claim 12 (depends on 7) The measuring assembly of claim 7, wherein the sleeve has a narrow portion capable of receiving a portion of a bearing. ### Claim 13 (depends on 7) The measuring assembly of claim 7, wherein the sleeve has a lock portion capable being abutted against a first bearing. ### Claim 14 (depends on 7) The measuring assembly of claim 7, wherein the sleeve has a lock portion capable being abutted against a plurality of bearings. ### Claim 15 (depends on 7) The measuring assembly of claim 7, wherein the sleeve has a plurality of narrow portions including: a first narrow portion capable of receiving a portion of a first bearing; and a second narrow portion capable of receiving a portion of a second bearing. ### Claim 16 A measuring assembly for measuring one or more dimensions of a pipe that has an inner surface, and an outer surface, the measuring assembly comprising: a housing capable of being disposed at least in part inside the pipe, the cylindrical housing having an inner housing space; a sleeve disposed in the inner housing space; a lock capable of inhibiting movement of the sleeve; and a probe rotatably coupled to the housing, wherein the probe is capable of providing one or more dimensions of the pipe. ### Claim 17 (depends on 16) The measuring assembly of claim 16, wherein the lock has a tapered outer surface. ### Claim 18 (depends on 16) The measuring assembly of claim 16, wherein the lock is disposed between the housing and the sleeve. ### Claim 19 (depends on 16) The measuring assembly of claim 16, wherein the lock has collapsible fingers. ### Claim 20 (depends on 16) The measuring assembly of claim 16, wherein the lock has collapsible fingers capable of being abutted against the sleeve.
