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 (10), a ball bearing (11) mounted in the housing, and an end cover (12) having a cylindrical flange (39) extending as a close fit through the inner bearing ring (31) and secured therein by abutments (41, 42) on the flange engaging opposite sides of the inner bearing ring (31). 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 (26, 27, 36, 37) 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 (13) compressed between the housing and the end cover. <IMAGE>
