ABSTRACT:
A bearing assembly has a mounting bracket with an annular cut-out for supporting a bushing cradle with outer walls of corresponding angular shape for supporting a correspondingly shaped half block bushing. A half block bushing is used to support a roller journaled thereon. The half block form of the bushing permits convenient disassembly of the bearing for replacement of parts, and has longer and more stable wear characteristics. The outer walls of the bushing cradle 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 metal clip lock is used to retain the bushing and cradle in position relative to the mounting bracket by spring pressure.
