A sliding door suspension system and a sliding door assembly for supporting a heavy sliding door from a door frame includes a rail horizontally mounted to the door frame. The suspension system includes a roller assembly which rollingly engages the rail and supports the heavy door. The roller assembly includes an axle or shaft having a bearing surface. The axle has at least one threaded end for securing the roller assembly and for attaching the roller assembly to a door hanger from which the heavy door is suspended. The roller assembly further includes a roller with a concentric hollow bore for seating a bearing assembly or bushing through which the axle extends in supportive engagement with the bearing assembly. The rail has a convex arcuate upper roller guide surface. The roller has a concave arcuate roller guide engaging surface which conforms to and engages the upper surface of the rail. The roller assembly also includes a door height and alignment adjusting member which threadably engages the axle. In one embodiment, the door height adjusting member comprises an eccentric sleeve, whereas in an alternative embodiment, the door height adjusting member comprises an adjuster block.
