Outboard Roller Chain

Outboard roller construction makes for a highly compact conveyor. The ability to flex backwards adds to this by allowing easy layout on the return side to save space. Since a large number of rollers can be installed, a conveyor can be easily made where small objects are placed directly with no pallet. Quick starting is also possible by installing a plastic brake.
