ABSTRACT:
A piston for a fluid-actuated, percussive, down-the-hole drill is provided with self-lubricating bearings and self-lubricating seals. The piston includes an elongated body member terminating in a front end and a back end and having a longitudinal bore therethrough. A bearing and seal combination is positioned adjacent each end of the piston and an undercut portion of the piston body extends therebetween. The bore and undercut portions of the body form a portion of fluid passageways in the drill, when the piston is reciprocated in the drill. The seals float in their grooves, being movable axially, radially and circumferentially. The bearings are substantially nonmovable axially and radially.
