A conveyor belt module () includes a movable hinge rod retainer () that can be opened and closed without tools. The movable hinge rod retainer facilitates opening and rejoining of the conveyor belt () at one or more dedicated locations. In a first position, the hinge rod retainer locks a hinge rod () withing a hinge rod passageway. A user can easily move the hinge rod retainer to a second position in which the hinge rod passageway is open to allow removal of the hinge rod.

A conveyor belt module has a conveying surface and a drive surface having a skewed drive edge for engaging a sprocket tooth. The skewed drive edge is skewed relative to the conveying surface. The skewed drive edge is formed on an interior drive surface in a sprocket pocket and&#x2014;or an exterior drive surface on a drive element. The skewed drive edge is parallel to a corresponding downwardly-angled drive shaft accommodating sprockets of increasing size for driving a radius conveyor belt formed of a plurality of conveyor belt modules with skewed drive edges.

Snap-on rollers for a conveyor belt. The snap-on roller may be snapped onto an axle or into a cavity of a conveyor belt module. Multi-piece snap-on rollers can be installed radially onto an axle on a conveyor belt and joined together in a puzzle pattern to form a complete roller that can rotate on the axle.

A modular roller-top conveyor belt and rollers for the belt. The roller-top belt has axles that are fixed relative to the module body. Each of the pieces of the multi-piece rollers can be installed radially onto an axle and joined together in a puzzle pattern to form a complete roller that can rotate on the axle. Parallel ridges extending across the width of the modules add stiffness to the belt.

Multi-piece rollers for a conveyor belt. First and second roller sections fit together to form a complete roller. The two roller sections together define a bore for receiving an axle. The bore and the periphery of the roller are formed in part by each of the first and second roller sections. The roller is assembled by sliding the two sections together in a direction perpendicular to the axle with the bore closing around the axle. The roller sections have fingers that interdigitate with each other to prevent axial separation of the first and second roller sections. The interdigitated fingers surround a majority of the bore.
