Abstract
A pipe end preparation and cutoff tool includes a generally annular, fixed housing and a relatively rotatable tool carrying ring that is connected to the housing by means of orthogonal sets of roller bearings travelling in continuous bearing races that are likewise disposed in orthogonal planes. The bearing arrangement enables the ring to transmit radial and thrust loads to the housing and the structural arrangement of elements is intended to prevent gross contamination of the bearing assemblies.
