ABSTRACT The invention relates to an idler roller particularly for conveyor belt support and comprises a prefabricated core member with bearing located at the ends of the core about which core and bearings there is moulded an abrasion and impact resistant load bearing synthetic plastic shell. The shell includes a tubular loud bearing wall and integral side walls having recesses in which are accommodated bearings which receive the idler shaft. By the utilisation of a relatively inexpensive core which does not require to possess load bearing properties, and utilising this core as a former about which the load bearing shell is moulded with bearings in situ, a satisfactory idler roller structure can be constructed relatively inexpensively. The shell should be moulded from a non-foamed polyurethane elastomer material to give high quality abrasion resistance coupled with impact resistance.
