A roller modular conveyor belt module for motorized continuous conveyors includes, first and second hinge elements extending from a main body along opposite directions orthogonal to the first direction and spaced from each other. Each of the hinge elements has a through hole with axis parallel to the first direction and being coaxial to each other to receive a respective hinge pin. The first hinge elements are adapted to interpose to second hinge elements of another module with through holes coaxial to each other to receive a hinge pin articulating therebetween. In the space between adjacent hinge elements, there is at least one roller passed through by an axial hole arranged coaxially with the through holes of the adjacent hinge elements delimiting the space. The module includes at least one bushing having an end portion inserted in the through hole, and extending through the roller axial hole.
