A DK conveyor chain includes a construction, as well as names on the elements are stated in the drawing. These parts have functions specified beneath.
Pins
Pins support the many load acting around the chain together with plates, and when the chain is engaged with the sprockets, they slide along with bushings as bearings. They are really subject to put on and particularly should have large shear strength, bending power and wear resistance. Hardened and tempered difficult steel, carburized steel, or induction-hardened steel is used.
Rollers
Rollers protect the chain from shocks together with the sprockets, and when the chain is engaged using the sprockets, the rollers bend the chain smoothly and act to reduce the resistance when the chain runs on the rail. These are essential to get high shock fatigue strength, collapse power and put on resistance. Hardened and tempered challenging steel, carburized steel or induction-hardened steel is utilized.
Bushings
Bushings are found among pins and rollers and act as bearings for the two the pins and rollers not to transmit the load obtained through the rollers directly to your pins when the chain is engaged using the sprockets. They may be necessary to possess high shock fatigue strength, collapse strength and dress in resistance, and generally, carburized steel is made use of.
Plates
Plates are subject to repeated tension in the chain and occasionally to substantial shocks. They’re demanded to possess higher tensile strength, and particularly higher shock strength and fatigue power. Substantial tensile steel is employed for normal chains and heat-treated 
alloy steel for heavy-duty chains.
T-pins
T-pins stop the outer plates from disengaging through the pins. They may be manufactured from soft steel since pins are typically pressed-in the outer plates and thus no huge force acts on the T-pins.
