A modular conveyor system (10) has a side flexing conveyor belt (12) having first and second sides. The belt (12) includes side links (22) each having a depending arm (24), an inwardly transverse tab (28), and curved skirts (26a, 26b) bridging gaps between adjacent side links (22) to engage each other in edge-to-edge contact to prevent sagging, to assist the belt (12) in ramping up and down, and to retain the belt (12) along a return run. In a curved section, the system (10) includes a passive guide rail (14) and an active guide rail (16). The passive guide rail (14) is on the first belt side and engages the tabs (28) thereat, and the active guide rail (16) is on the second belt side and has drag-reducing roller assemblies (18) engaging the tabs (28) thereat. Each roller assembly (18) has an upper roller (38) and a lower roller (40) each having a pair of spaced disks defining a circumferential groove (42, 44) for engaging the tabs (28).
