  • Pin joint component with improved wear surfaces
    Patent number: 9073589
    Abstract: The present disclosure is directed to a pin joint component for a pin joint assembly that has improved wear surfaces, especially for those portions of the pin joint component surface that interface thrust rings, lips, and other adjacent wear components. The pin joint component comprises a first treated region that is formed by removing material from the wear surface of the pin joint component and replaced with clad material. Prior to this operation, a second treated region is formed by removing material from a section of the pin joint component distinct from the first treated region and performing a nitriding process thereon.
