A conveyor roller for supporting conveyor belts is of simple construction and incorporates five main elements. There is an outer cylindrical member on which the conveyor belt rides in use and an axial hollow shaft extending axially of the roller. At each end of the assembly is a housing member attached to the cylindrical member and a central fixed member between which the axial shaft extends and which is attached thereto. A bearing is located between the housing member and the fixed member in each case and these parts are also sealed in relation to one another. The fixed member is an integral unit having a stub shaft at one axial end for connection to the axial shaft and, at the other end, means for supporting the roller on fixed supports. The fixed member also extends outwardly to adjacent the cylindrical member. The roller is simple to construct and assemble using simple components.
