Four chain widths, and what changes with them
The range is S520 at 62 mm, S530 at 83 mm, S540 at 140 mm and S560 at 220 mm chain. Width is the first decision and it drags three others with it. The S520 has a 30 mm chain pitch and runs quietest; the other three share a 38 mm pitch. Profile width tracks the chain closely at 64, 86, 141 and 224 mm, so the space the conveyor occupies is roughly the chain width plus a couple of millimetres. Pick the width from the footprint of your product, then check what it costs you in the next two sections.
