Double flex chains are made for a variety of conveying applications. They are widely used in the dairy and forest industries. They are designed to run in-floor multi-directional applications and are induction hardened in all critical wear areas.
Industries
Pins and center links are made of heat treated alloy steel. Pins are induction hardened for increased wear resistance and longer life. Center links are also induction hardened on the edges for increased wear. Sidebars are made of medium carbon heat treated steel and the edges are induction hardened. DF3500 sidebars are also induction hardened on the sliding face to further increase life.
Double flex chains are riveted construction. Connecting pins are also riveted.
Double flex chains are interchangeable with other standard makes of corresponding sizes and numbers.
Double flex chains are primarily used in the dairy and forest product industries. The conveyors are usually multiple strands, moving boards and crates around corners.
Double flex chains are best suited for slow or moderate speed applications. Maximum chain speed depends upon size of sprockets. For Conveyor Service see the Table below.
