A DK conveyor chain has a structure, and the names with the elements are stated from the drawing. These parts have functions specified below.
Pins
Pins help all of the load acting over the chain together with plates, and once the chain is engaged with the sprockets, they slide together with bushings as bearings. They’re topic to put on and particularly should have substantial shear power, bending 
power and dress in resistance. Hardened and tempered tough steel, carburized steel, or induction-hardened steel is employed.
Rollers
Rollers guard the chain from shocks with all the sprockets, and once the chain is engaged with the sprockets, the rollers bend the chain smoothly and act to lessen the resistance once the chain runs on the rail. They may be expected to get substantial shock fatigue power, collapse strength and put on resistance. Hardened and tempered hard steel, carburized steel or induction-hardened steel is utilised.
Bushings
Bushings are positioned between pins and rollers and act as bearings for both the pins and rollers not to transmit the load acquired by the rollers directly for the pins once the chain is engaged with all the sprockets. They may be demanded to have high shock fatigue power, collapse strength and put on resistance, and usually, carburized steel is employed.
Plates
Plates are topic to repeated stress with the chain and at times to massive shocks. They are required to possess substantial tensile strength, and particularly substantial shock power and fatigue strength. Higher tensile steel is made use of for normal chains and heat-treated alloy steel for heavy-duty chains.
T-pins
T-pins avert the outer plates from disengaging in the pins. They are really made from soft steel considering the fact that pins are normally pressed-in the outer plates and so no significant force acts over the T-pins.
