ABSTRACT:
A bearing assembly has first and second trunnions supporting a bearing and defining a trunnion pivot axis. In the improvement, each of the trunnions is mounted in and supported by a separate cushion member of annular shape. The assembly permits bearing pivoting about the trunnion pivot axis (i.e., about the X axis) and the cushion members permit limited freedom of movement of the trunnions in axes (i.e., the Y and/or Z axes) which are angular to the pivot axis. The new bearing assembly is ideal for use on an earth-working implement such as a disc harrow.
