ABSTRACT:
A full support bearing for a grader circle including a first radial groove in a cylindrical portion of the circle includes a group of inserts forming a second support groove within the first radial groove. It also includes circle supports sized and shaped such that the gap between any two circle supports is small. The circle supports are arranged along a circumference of the circle and rigidly attached to a draw bar. The arrangement results in virtual 360 degree circle support, lower loads, and smaller material deflections at all loaded areas, and significantly increased durability due to a resultant reduction in wear rates.
