An idler 100 (e.g. for a conveyor belt installation) includes plural sleeve segments 102.1 -102.5 which constitute an outer sleeve 102. More specifically, the idler 100 has a central axle 104 and a bearing surface provided concentrically with and radially outwardly from the axle 104. The idler 100 is characterised in that it has a plurality of sleeve segments 102.1 - 102.5 which fit together end-to-end thereby to define a cylindrical segmented sleeve 102 which presents the bearing surface, at least some of the sleeve segments 102.1 -102.5 having an inner radially extending support 204 wall thereby to support the segmented sleeve 102 intermediate its ends. |
