摘要
A conveyor trolley assembly consisting of a trolley bracket having an axle carrying a hub, and an annular wheel carried on a bearing interposed between the hub and the wheel, is provided with a four-part, moisture resistant seal for the side of the bearing facing the trolley bracket. The seal is composed of an annular shield mounted on the axle and interlocked with the trolley bracket, a slinger seal mounted on the wheel inside of the shield, and second and third lubricant seals mounted on the wheel hub and on the wheel, respectively. Moisture which enters around the periphery of the shield either gravitates to a drain opening or is expelled by the action of the slinger seal.
