Abstract
To increase the self-supporting lengths and to achieve a higher load-bearing capacity for an energy guide chain, there is proposed a chain link which has two spaced-apart, mutually oppositely disposed, plate-shaped chain link portions (9) and at least one transverse portion connected to the chain link portions (9). At least one chain link portion (9) has a core (1). The core (1) is enclosed by a core sheathing (10). The core (1) is such that it has a higher level of strength than the core sheathing (10). It is proposed that the core (1) comprises a metallic material. The core sheathing comprises a plastics material.
