A wash arm hub for a dishwasher includes a sealed bearing rotatably coupling first and second mounting hub members. The sealed bearing, as well as the first and second hub members, define an interior fluid passageway or chamber to permit fluid to flow through the hub assembly. The sealed bearing and the design of the hub members prevents fluid leakage out of the hub, thereby providing a low friction support for a wash arm and a sealed connection between a fluid supply and the wash arm.
