Abstract A boring apparatus having a working member mounted for rotation on a lubricated bearing about a shaft member, the apparatus being of the type in which substantial radial and axial relative motion between said members occurs in response to radial and axial loading conditions encountered by the working member during operation in an abrasive laden external environment, in- cluding an improved seal assembly between the members for sealing the bearing from the environment while accommodating the radial and axial relative motion, the seal assembly comprising a seal carrier mounted in a space between the members, a dynamic seal element supported between the carrier and one of the members to form a dynamic seal therebetween, and a static seal element sup- ported between the carrier and a radially extending surface of the other of the members, the dynamic seal element being axially slidable along the one member to accommodate the axial relative motion, the static seal element being deformable and radially slidable along the surface to accommodate said radial relative motion.
