General information

Round steel chain HE / Profile steel chain HEP

Type RAS, RDS, RD

Different using conditions need different chains. To ensure an optimal relation between costs and benefits of your use, we distinguish our case hardened chains by three types. The chains are adapted to the requirements through a special heat treatment technology.
