1. An energy chain to guide at least one line, comprising:
a plurality of chain links flexibly connected to each other, which each comprise lateral link plates parallel to one another and cross webs connecting the lateral link plates,
wherein the energy chain is displaceable such that the plurality of chain links forms opposite strands as upper and lower strands, and a deflection area connecting the upper strand and the lower strand,
wherein, to facilitate a rolling action when the energy chain is displaced, rollers are provided on at least some of the plurality of chain links of the upper strand and/or the lower strand, which project beyond narrow sides of the lateral link plates in a direction of the respectively opposite strand,
wherein each of the rollers comprise a wheel body made of plastic with a hub, a rim and a radial region connecting the hub and the rim, wherein a material thickness of the radial region is reduced compared with the rim such that radial impacts during the rolling action are dampable by elastic deformability of the radial region.

25. An energy chain to guide at least one line, comprising:
two link plate strands comprising alternating inner link plates and outer link plates, which are connected swivelably to each other by flexible connections,
wherein at least some of the outer link plates have cross webs holding the outer link plates respectively parallel to one another,
wherein the energy chain is displaceable such that the energy chain forms opposite strands as upper and lower strands, and a deflection area connecting the upper strand and the lower strand,
wherein, to facilitate a rolling action when the energy chain is displaced, at least the upper strand and/or the lower strand comprises a plurality of rollers, which project beyond narrow sides of the inner and outer link plates in a direction of the respectively opposite strand,
wherein each roller is arranged respectively on a pair of outer link plates of the outer link plates, comprising a first outer link plate and an adjacent second outer link plate, swivelable in relation to one another, and the flexible connection of the pair of outer link plates comprises a joint pin, which is formed in one piece with the first outer link plate, and a corresponding joint mount, which is formed by the second outer link plate, wherein the joint pin engages in the joint mount and is swivelable therein,
wherein the second outer link plate has a sleeve-like annular projection coaxial with a swivel axis, wherein the sleeve-like annular projection forms the joint mount, on which each roller is supported rotatably with a rotary axis of the roller coaxial with the swivel axis.

30. A roller assembly of an energy chain, comprising:
a pair of lateral link plates, which are flexibly connected to one another and each comprise two narrow sides, and
a roller arranged on the pair of lateral link plates, which is arranged such that the roller projects beyond a narrow side of the lateral link plates, to facilitate a rolling action when the energy chain is displaced,
wherein the roller comprises a wheel body made of plastic with a hub, a rim and a radial region connecting the hub and the rim, wherein a material thickness of the radial region is reduced compared with the rim such that radial impacts during the rolling action are dampable by elastic deformability of the radial region.
