Abstract: A coupling (1) for links (2, 3) of tracks, which comprises a pin (4) which is integral with at least one first link (2), and a bushing (5), fitted rotatably over the pin (4), which is integral with at least one second link (3). The pin (4) comprises a cylindrical central portion (6) which has a first predefined diameter and two end portions (7) which have a second predefined diameter; the first predefined diameter is larger than the second predefined diameter. The pin (4) comprises an axial non-through channel (8) connected to the outside at one of its ends, and a substantially radial passage (10) between the outer lateral surface of its central portion (6) and the inner channel (8). The bushing (5) comprises a through hole with a diameter which is larger than and proximate to the outside diameter of the central portion (6) of the pin (4), on which it is arranged in the assembled configuration. The pin (4) supports, substantially proximate to the end portions of the central portion (6), respective means for sealing and alignment (12) which abut on respective end fronts (13) of the bushing (5), for the confinement of the fluid lubricant interposed between the pin (4) and the bushing (5).

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.
