A long distance cable chain is provided to reduce frictional noise and vibration caused by a rolling element by installing the rolling element at a side of a link body. A long distance cable chain comprises a first link body(10) and a second link body(20). The first link body includes a pair of first plates(11) and a cross member(13) coupled to upper/lower sides of the first plates. A first joint post(12) is projected from a first end of the first plate. A first accommodation groove is formed at a second end of the first plate. The second link body jointed with the first link body includes a second plate(21) and a rolling contact member(30) selectively provided at an upper side and a lower side of the second plates. A second joint post(22) is projected from a first end of the second plate. A second accommodation groove is formed at a second end of the second plate into which the first joint post is inserted.
