A bearing assembly has a half block bushing for supporting a roller journal thereon, with outer walls having an angular shape which fits into a correspondingly shaped bushing cradle mounted to a mounting bracket. The half block form of the bushing permits convenient manufacture and disassembly of the bearing for replacement of parts, and has longer and more stable wear characteristics. The outer walls of the bushing are preferably trapezoidal to prevent rotational movement of the bushing relative to the cradle and mounting bracket, and to permit easy removal of the bushing during replacement. A spring wire clip lock is used to retain the bushing and cradle in position relative to the mounting bracket by spring pressure.
