A conveyor belt module includes a body, a link end formed by the body, and an opening through the link end along a hinge axis. A cover extends from the body in a direction of the hinge axis and a post extends from the cover; a bearing is rotatably engaged with the post. A fastener engages the post to capture the bearing between the cover and the fastener, such that the bearing is housed at least partially between the upper and lower extremes of the body. A track for supporting and guiding the conveyor belt module includes a guide arm extending into a guide channel defined by the body to engage the bearing. The conveyor belt module may also include laterally offset protrusions extending from the link end in opposite directions to inhibit engagement with a drive member.
