Abstract: A seal ring for a seal assembly includes a body and a seal flange. The body is generally cylindrical and extends along a longitudinal axis between a load end and a seal end. The seal flange is disposed at the seal end of the cylindrical body. The seal flange circumscribes the body and projects radially from the body to a distal perimeter of the seal flange. The seal flange includes a sealing face which is annular and disposed adjacent the distal perimeter. The seal ring is made from an alloy that includes between 6 percent and 9 percent by weight of iron, between 1.5 percent and 3 percent by weight of silicon, greater than 14 percent by weight of chromium, and at least 65 percent by weight of nickel.

Abstract: A ground engaging tooth for a ground engaging machine is disclosed. The ground engaging tooth may comprise a non-ground-engaging end, a ground-engaging end, a body extending between the non-ground-engaging end, the ground-engaging end, a top surface, a bottom surface, a left surface and a right surface. Further, the ground engaging tooth may comprise a coupling side including a pocket configured to receive a retaining device. Moreover, the ground engaging tooth may comprise a wear side including an integral-wear-insert. The integral-wear-insert may longitudinally extend along the bottom surface towards the ground-engaging end and vertically extend towards the top surface at the ground-engaging end.
