The present invention relates to a roller assembly of a multiple speed chain and, more specifically, relates to a roller assembly of a multiple speed chain, which comprises: a center roller which is in contact with a lower end surface of a pallet; a side roller which is in both sides of the center roller; and a chain bush which becomes a rotation central axis of the center roller and the side roller. As the side roller which is in both sides of the center roller has a mutually integrated structure, in a production line wherein a multiple speed chain including the roller assembly according to the present invention is installed, a speed of a transfer object is stable. Moreover, when operating the line, an initial acceleration time is significantly short, and further, a faster moving speed is shown under the same motor driving force compared to the past. |
