Abstract
A seal arrangement for use in a track joint having a track pin and a cylindrical bushing on the pin and two track links. The end of the bushing and one of the track links present annular surfaces faced toward each other and spaced apart. The seal arrangement includes a seal ring of elastomer material and a thrust ring of rigid material. The seal ring has a body portion and two radially outwardly extending leg portions which contact the annular surfaces. The thrust ring is molded into the body portion of the seal ring and includes a plurality of cooperating axial recess portions and radial recess portions formed therein. The elastomer material of the seal ring extends into and fills the recess portions so as to form circumferentially spaced integral link portions around the thrust ring.
