Abstract
An improved bush assembly for insertion into an aperture of a lug of a track part of a tracked vehicle is disclosed. An exposed outermost side wall of the bush has an extended surface length, so that when under design precompression the wall makes angles of approximately 90.degree. with the inner surface of the aperture and 70.degree.-80.degree. with the outer surface of the central pin. The wall may be concave and the bush may comprise a number of annular bush parts. The high tensile strains which develop on that wall of the bush are thereby minimized and bulging out of the bush beyond the end of the pin is discouraged.
