A DK conveyor chain has a construction, plus the names on the elements are stated inside the drawing. These parts have functions specified beneath.
Pins
Pins support every one of the load acting over the chain together with plates, and when the chain is 
engaged with the sprockets, they slide along with bushings as bearings. They can be topic to wear and especially have to have higher shear power, bending strength and dress in resistance. Hardened and tempered challenging steel, carburized steel, or induction-hardened steel is utilized.
Rollers
Rollers safeguard the chain from shocks with the sprockets, and once the chain is engaged together with the sprockets, the rollers bend the chain smoothly and act to reduce the resistance once the chain runs on the rail. They can be necessary to possess high shock fatigue power, collapse strength and dress in resistance. Hardened and tempered hard steel, carburized steel or induction-hardened steel is applied.
Bushings
Bushings are positioned between pins and rollers and act as bearings for the two the pins and rollers not to transmit the load acquired through the rollers immediately to the pins once the chain is engaged with all the sprockets. They are really required to get substantial shock fatigue power, collapse strength and dress in resistance, and generally, carburized steel is utilised.
Plates
Plates are topic to repeated tension with the chain and at times to massive shocks. They are demanded to get large tensile strength, and particularly higher shock power and fatigue strength. Higher tensile steel is utilized for common chains and heat-treated alloy steel for heavy-duty chains.
T-pins
T-pins avert the outer plates from disengaging through the pins. They’re made from soft steel considering that pins are commonly pressed-in the outer plates and as a result no big force acts within the T-pins.
