A DK conveyor chain has a structure, as well as names from the components are stated while in the drawing. These components have functions specified beneath.
Pins
Pins assistance each of the load acting to 
the chain together with plates, and when the chain is engaged with all the sprockets, they slide along with bushings as bearings. These are subject to dress in and especially ought to have higher shear strength, bending power and dress in resistance. Hardened and tempered challenging steel, carburized steel, or induction-hardened steel is employed.
Rollers
Rollers shield the chain from shocks using the sprockets, and when the chain is engaged using the sprockets, the rollers bend the chain smoothly and act to lessen the resistance once the chain runs on a rail. These are needed to get high shock fatigue strength, collapse strength and wear resistance. Hardened and tempered hard steel, carburized steel or induction-hardened steel is utilized.
Bushings
Bushings are found amongst pins and rollers and act as bearings for each the pins and rollers not to transmit the load obtained from the rollers directly for the pins once the chain is engaged using the sprockets. They may be required to get higher shock fatigue power, collapse strength and wear resistance, and usually, carburized steel is utilized.
Plates
Plates are subject to repeated tension on the chain and at times to big shocks. They’re essential to possess substantial tensile strength, and particularly substantial shock power and fatigue strength. High tensile steel is employed for conventional chains and heat-treated alloy steel for heavy-duty chains.
T-pins
T-pins reduce the outer plates from disengaging from the pins. They’re made of soft steel due to the fact pins are generally pressed-in the outer plates and hence no substantial force acts on the T-pins.
