The roller according the invention is suitable for use with an endless belt conveyor or the like. Known rollers for conveyors are disadvantageous in that in the event of a roller or shaft being damaged, the entire roller must be replaced. This can be a time consuming operation. The roller (10) according to the invention is mounted between end supports providing bearing (16) comprising a shield (18) for each bearing. Each shield comprises a convex cup-shaped formation for engagement in a recess (20) in each roller end wall (22). The cup-shaped formation defines an annular skirt (24) adapted to house a conventional roller bearing (16) coupled to the end support by way ofashaft (26). A washer (28) is provided on the shaft (26) between the shaft (26) and a dust cover (30). With this arrangement the roller may readily be removed when a damaged roller must be repaired.
