A grain combine for threshing grain from crop has a threshing rotor within a rotor housing (6), a front plate (8) with a crop entry hole (10), a stationary ring (12) mounted on the rearward side of the front plate, a plastic bearing pad (26) mounted on the outer surface of the stationary ring, and a rotating ring (14) mounted to the forward end of the rotor housing which lands on the bearing pad, thereby supporting the rotor housing. The bearing pad has a soft, elastomeric inner layer (30) adjacent to the stationary ring, and a hard, elastomeric outer layer (28) adjacent to the rotating ring. In addition, the rotating ring has a plurality of holes (32) that allow dirt or other foreign material to exit the rotor housing. <IMAGE> |
