ABSTRACT:
A free-flow conveyor chain having a pin received by a chain element and a supporting roller for supporting an article being transmitted. The chain element is moved along a guide rail and an O-ring, excellent in resiliency, is interposed between the supporting roller and frictional element for preventing the supporting roller from dropping off the pin. The element is press-fitted to an end portion of the pin and engages an O-ring carried by the supporting roller. Thus, a frictional braking torque is applied to the supporting roller.
