A DK conveyor chain includes a construction, and the names on the components are stated in the drawing. These parts have functions specified beneath.
Pins
Pins help the many load acting about the chain along with plates, and when the chain is engaged together with the sprockets, they slide along with bushings as bearings. They can be topic to wear and especially need to have substantial shear strength, bending power and put on resistance. Hardened and tempered challenging steel, carburized steel, or induction-hardened steel is made use of.
Rollers
Rollers guard the chain from shocks with all the sprockets, and once the chain is engaged together with the sprockets, the rollers bend the chain smoothly and act to reduce the resistance when the chain runs on a rail. They’re necessary to have higher shock fatigue power, collapse power and wear resistance. Hardened and tempered difficult steel, carburized steel or induction-hardened steel is employed.
Bushings
Bushings are found amongst pins and rollers and act as bearings for both the pins and rollers not to transmit the load received by the rollers immediately on the pins when the chain is engaged with the sprockets. They are required to get high shock fatigue power, collapse power and dress in resistance, and generally, 
carburized steel is made use of.
Plates
Plates are topic to repeated stress of your chain and sometimes to significant shocks. They may be demanded to possess high tensile strength, and particularly higher shock strength and fatigue power. High tensile steel is employed for standard chains and heat-treated alloy steel for heavy-duty chains.
T-pins
T-pins prevent the outer plates from disengaging through the pins. They can be made of soft steel considering that pins are commonly pressed-in the outer plates and thus no substantial force acts on the T-pins.
