  • Publication number: 20100167858
    Abstract: In a seal chain having ring-shaped seals sealed between outer plates and inner plates, by reducing the thickness of the outer plates and the inner plates, a distance between inner side surfaces of the both inner plates and a distance between outer side surfaces of the both outer plates are set to be same as those of a standard chain, and the length of pins is set to be same as that of the standard chain, so that a narrow seal chain in which a standard guide can be used, and a standard attachment can be attached is achieved.
