Abstract
A conveyor roller comprises a roller tube fitted with end cap assemblies incorporating bearings for rotatably mounting the roller tube on a fixed shaft. Each end cap assembly is a self-contained unit comprising a housing, a ball bearing mounted in the housing, and an end cover having an annular flange extending as a close fit through the inner bearing ring and secured therein by abutments on the flange engaging opposite sides of the inner bearing ring. The end cover has a central bore for reception of the shaft as a close sliding fit. The housing and the end cover have annular concentric tongues which are interleaved to form an annular labyrinth passageway providing a seal between the housing and the end cover. The inner end of the labyrinth passageway is closed by an annular seal compressed between the housing and the end cover.
