A DK conveyor chain includes a framework, as well as the names in the components are stated during the drawing. These parts have functions specified under.
Pins
Pins help the many load acting about the chain together with plates, and once the chain is engaged with the sprockets, 
they slide along with bushings as bearings. They may be topic to dress in and particularly ought to have high shear power, bending strength and wear resistance. Hardened and tempered challenging steel, carburized steel, or induction-hardened steel is applied.
Rollers
Rollers protect the chain from shocks together with the sprockets, and once the chain is engaged with the sprockets, the rollers bend the chain smoothly and act to lessen the resistance once the chain runs on the rail. They can be necessary to get higher shock fatigue power, collapse power and put on resistance. Hardened and tempered challenging steel, carburized steel or induction-hardened steel is utilised.
Bushings
Bushings are positioned between pins and rollers and act as bearings for the two the pins and rollers to not transmit the load acquired by the rollers directly for the pins once the chain is engaged using the sprockets. They may be necessary to possess large shock fatigue power, collapse strength and put on resistance, and normally, carburized steel is applied.
Plates
Plates are topic to repeated tension on the chain and in some cases to big shocks. They can be essential to possess substantial tensile strength, and especially high shock strength and fatigue power. Substantial tensile steel is made use of for normal chains and heat-treated alloy steel for heavy-duty chains.
T-pins
T-pins protect against the outer plates from disengaging from your pins. They are made of soft steel since pins are generally pressed-in the outer plates and hence no substantial force acts about the T-pins.
