Special Small Conveyor Chain, Hollow Pin Double Pitch Chain

Chain with holes added to its pins that can be used to mount various attachments. Used for transport. The attachment center distance does not change regardless of whether the sprocket has engaged - even if the chain is on a straight line. Attachment is balanced for both plates. This is advantageous even for strong surfaces, as it suppresses meandering while the chain runs. Attachment replacement, maintenance, and interval changes can be easily performed, even with the chain still mounted to equipment.
