Abstract: An enclosed track conveyor chain assembly and method of construction includes a plurality of guide link assemblies and load link assemblies connected to form a conveyor chain assembly. Each load link assembly includes a pair of side walls and forward and rearward ends defining an opening. A pair of wheel assemblies supports the load link on the horizontal surfaces of the track. A guide link member is inserted into the opening of adjacent load links. Distal ends of the guide links are connected via a fastener to thereby connect adjacent load link members to form the enclosed track chain. Each guide link member includes a plurality of flat areas on the distal ends of the arms to provide a connecting surface. A fastener is inserted through openings in the distal ends to secure the guide link members together. Preferably, the connection between guide link members is pivotal to allow pivoting action of the guide link.

Abstract: A trolley wheel assembly (10) securely sealed to prevent loss of lubricant therefrom and entrance of contaminants therein. The assembly (10) comprises an inner race (12) disposed about an axis of rotation (14) and an outer race (16) concentrically disposed in a spaced relationship about the inner race (12). A plurality of ball bearings (18) are disposed between the inner race (12) and the outer race (16). An outer sealing ring (20) extends radially inwardly from the outer race (16) toward the inner race (12). An inner sealing ring (22) is rotatably disposed about the inner race (12), extending radially outwardly and contiguous the outer sealing ring (20). A wave washer (24) disposed about the inner race (12) biases the inner sealing ring (22) into constant friction engagement with the outer sealing ring (20). A plurality of backup inner sealing rings (26,27) provide a secondary seal about the inner race (12).
