Free Flow Conveyor Chains

Free Flow Conveyor Chains are also referred as double plus chains, triple speed conveyor chains or accumulation chains or fly roller chains. Products are available both in carbon steel and stainless steel, and are widely applied in the electronics industry to transport consumer products like TVs, VCRs and radios, etc. Rollers can be plastic, carbon steel and stainless steel ones. Safety is ensured by the extra-large, engineering plastic center rollers which allow for installation on a chain cover. For harsh working environment, extra-large steel rollers are recommended.
