ABSTRACT:
A track bushing for use with a track assembly of a track-type machine includes a generally cylindrical member having ends adapted for mounting in opposing end portions of a track link and a longitudinal bore extending between the ends. The inner surface of the bore defines first and second load bearing portions at each of the ends. Each of the first load bearing portions define a first conical surface tapering radially inward from each of the ends at a first angle, and each of the second load bearing portions define a second conical surface tapering radially inward from each of the first conical surfaces at a second angle. In the bushing's assembled state, the first angle is in the range of 0.09 degrees to 0.18 degrees and the second angle is in the range of -0.01 degrees to 0.01. In the bushing's free state, the first angle is in the range of 0.19 degrees to 0.27 degrees and the second angle is in the range of 0.06 degrees to 0.08 degrees.
