Abstract
The present invention includes a chain link for an energy guide chain for receiving cables, hoses. The chain link includes elongate side walls and transverse web portions connecting same. Each side wall has sliding surfaces for movable connection to a side portion of an adjacent chain link. The sliding surfaces, which slide against each other, of adjacent chain links are formed of a different material. At least part of the sliding surfaces is produced by an additional body, which are formed from a different material from the side wall. The additional body is attached to at least one side wall prior to assembly of the energy guide chain. The additional body is mounted to the chain link prior to and not during assembly of the energy guide chain. This operation permits the chain links to be fitted together in an uncomplicated manner and promotes automated assembly procedures.
