Abstract: An energy chain comprising rollers on a number of chain links of the upper strand and/or of the lower strand. The rollers project, at least to a slight extent, beyond narrow sides of the lateral plates in the direction of the respectively opposite strand, in order to allow for rolling action when the energy chain is displaced. The invention provides for the rollers to comprise a wheel body made of plastic and having a hub, a rim and a radial region, which connects the hub and rim. The material thickness of the radial region is reduced in comparison with the rim such that radial impacts during the course of the rolling action can be damped by elastic deformability of the radial region of the roller itself. This significantly reduces the development of noise and vibration caused by rollers located opposite one another coming into contact with one another.
