Abstract: A modular conveyor belt module incorporating balls or rollers in the belt module, where the module is adapted for installation in a modular conveyor belt, where the conveyor belt is of the type assembled from a plurality of substantially identical modular belt links where one or more modular belt links forms lateral rows, and where a plurality of eye parts extend forwards and rearwards from the main body, the eye parts being spaced in a width direction of the modular belt link creating an opening between adjacent eye parts, such that when two modular conveyor belt links are pushed together, the eye parts on one link will inter-fit between eye parts on the other modular belt link, and where lateral apertures in all eye parts are provided, such that when the eye parts of modular belt links in one row are overlapping eye parts in an adjacent row.
