A DK conveyor chain includes a construction, as well as names with the parts are stated within the drawing. These parts have functions specified under.
Pins
Pins help all of the load acting on the chain along with plates, and when the chain is engaged using the sprockets, they slide together with bushings as bearings. They’re subject to dress in and especially have to have higher shear strength, bending power and dress in resistance. Hardened and tempered difficult steel, carburized steel, or induction-hardened steel is employed.
Rollers
Rollers protect the chain from shocks using the sprockets, and once the chain is engaged with all the sprockets, the rollers bend the chain smoothly and act to lessen the resistance when the chain runs on a rail. They’re needed to possess substantial shock fatigue power, collapse strength and put on resistance. Hardened and tempered challenging steel, carburized steel or induction-hardened steel is made use of.
Bushings
Bushings are located in between pins and rollers and act as bearings for both the pins and rollers not to transmit the load obtained through the rollers right for the pins when the chain is engaged with the sprockets. They can be required to have higher shock fatigue strength, collapse strength 
and put on resistance, and usually, carburized steel is applied.
Plates
Plates are subject to repeated stress with the chain and occasionally to substantial shocks. They’re expected to have large tensile strength, and especially high shock power and fatigue strength. Large tensile steel is employed for common chains and heat-treated alloy steel for heavy-duty chains.
T-pins
T-pins avert the outer plates from disengaging from your pins. These are made of soft steel given that pins are normally pressed-in the outer plates and as a result no substantial force acts around the T-pins.
