A DK conveyor chain includes a structure, along with the names of the components are stated in the drawing. These components have functions specified beneath.
Pins
Pins help all the load acting on the chain together with plates, and when the chain is 
engaged using the sprockets, they slide along with bushings as bearings. They’re topic to wear and especially should have high shear power, bending power and dress in resistance. Hardened and tempered challenging steel, carburized steel, or induction-hardened steel is made use of.
Rollers
Rollers defend the chain from shocks using the sprockets, and once the chain is engaged with the sprockets, the rollers bend the chain smoothly and act to lessen the resistance when the chain runs on the rail. These are demanded to get high shock fatigue strength, collapse strength and wear resistance. Hardened and tempered hard steel, carburized steel or induction-hardened steel is applied.
Bushings
Bushings are located involving pins and rollers and act as bearings for the two the pins and rollers not to transmit the load received from the rollers right on the pins when the chain is engaged together with the sprockets. They may be needed to get large shock fatigue power, collapse power and put on resistance, and in general, carburized steel is utilised.
Plates
Plates are topic to repeated stress of the chain and sometimes to huge shocks. They are really necessary to have high tensile strength, and particularly substantial shock strength and fatigue strength. Higher tensile steel is applied for typical 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 really made of soft steel given that pins are normally pressed-in the outer plates and hence no significant force acts on the T-pins.
