ABSTRACT:
A cannon barrel assembly has a barrel member centered on and extending along a barrel axis, a barrel tube member generally coaxially surrounding the barrel and having a pair of axially opposite tube muzzle and breech ends, and respective muzzle and breech bearings at the tube ends axially displaceably supporting the barrel member therein. At least one of the bearings comprises two lower and one upper segmental slide elements generally angularly equispaced about the axis and radially set in one of the members against axial displacement therein. The two lower elements are also set in the one member against radial displacement therein while the upper element is limitedly radially displaceable in the one member. Springs braced between the one member and the upper slide element urge same radially against the other member in surface contact therewith and thereby urge the two lower slide elements in surface contact against the other member also.
