A DK conveyor chain includes a framework, plus the names from the parts are stated inside the drawing. These elements have functions specified below.
Pins
Pins help all the load acting on the chain along with plates, and when the chain is engaged using the sprockets, they slide along with bushings as bearings. They are really topic to dress in and especially need to have large shear strength, bending power and wear resistance. Hardened and tempered hard 
steel, carburized steel, or induction-hardened steel is made use of.
Rollers
Rollers shield the chain from shocks together with the sprockets, and once the chain is engaged together with the sprockets, the rollers bend the chain smoothly and act to lessen the resistance when the chain runs on the rail. They’re necessary to possess higher shock fatigue power, collapse strength and wear resistance. Hardened and tempered difficult steel, carburized steel or induction-hardened steel is employed.
Bushings
Bushings are positioned between pins and rollers and act as bearings for the two the pins and rollers not to transmit the load obtained by the rollers straight on the pins once the chain is engaged with all the sprockets. They’re needed to have high shock fatigue strength, collapse power and dress in resistance, and usually, carburized steel is utilised.
Plates
Plates are subject to repeated stress of the chain and occasionally to big shocks. They are essential to have large tensile strength, and especially high shock power and fatigue strength. High tensile steel is employed for common chains and heat-treated alloy steel for heavy-duty chains.
T-pins
T-pins stop the outer plates from disengaging in the pins. They are manufactured from soft steel because pins are commonly pressed-in the outer plates and so no big force acts over the T-pins.
