A DK conveyor chain includes a framework, as well as the names with the elements are 
stated during the drawing. These components have functions specified under.
Pins
Pins support each of the load acting within the chain along with plates, and when the chain is engaged together with the sprockets, they slide together with bushings as bearings. These are topic to dress in and particularly should have large shear power, bending power and dress in resistance. Hardened and tempered difficult steel, carburized steel, or induction-hardened steel is utilized.
Rollers
Rollers secure the chain from shocks together with 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 the rail. They can be necessary to possess higher shock fatigue power, collapse strength and put on resistance. Hardened and tempered hard steel, carburized steel or induction-hardened steel is made use of.
Bushings
Bushings are situated among pins and rollers and act as bearings for each the pins and rollers not to transmit the load obtained from the rollers right towards the pins once the chain is engaged together with the sprockets. They can be necessary to get large shock fatigue strength, collapse power and dress in resistance, and normally, carburized steel is utilised.
Plates
Plates are subject to repeated tension with the chain and in some cases to big shocks. These are required to get high tensile power, and particularly large shock power and fatigue strength. Large tensile steel is applied for standard chains and heat-treated alloy steel for heavy-duty chains.
T-pins
T-pins protect against the outer plates from disengaging from the pins. They are made of soft steel because pins are normally pressed-in the outer plates and as a result no large force acts on the T-pins.
