ABSTRACT:
A portable lathe tool includes fixed and rotating split rings, the fixed ring arranged to be secured to a pipe workpiece, the rotating ring being relatively rotatable with respect thereto for carrying a tool capable of performing a machining operation on the workpiece as it is driven around the circumference of the latter. A bearing arrangement for supporting the relatively rotating ring on the fixed ring is disclosed as having a plurality of discreet, circumferentially spaced bearing segments, each having converging radial and thrust bearing surfaces for engaging the rear end area of the rotating ring for axially, radially and rotationally locating and guiding the rotating ring relative to the fixed ring. An adjustment system is provided for accurately locating and adjusting the position of each of the bearing segments ring relative to the fixed ring to permit compensation for wear and dimensional variations.
