A DK conveyor chain has a framework, along with the names with the elements are stated while in the drawing. These elements have functions specified under.
Pins
Pins help all the load acting over the chain together with plates, and once the chain is engaged with all the sprockets, they slide together with bushings as bearings. They are really topic to wear and particularly will have to have high shear strength, bending power and wear resistance. Hardened and tempered challenging steel, carburized steel, or induction-hardened steel is utilised.
Rollers
Rollers protect the chain from shocks with all the sprockets, and when the chain is engaged with the sprockets, the rollers bend the chain smoothly and act to reduce the resistance when the chain runs on the rail. These are needed to get high shock fatigue power, collapse strength and wear resistance. Hardened and tempered hard steel, carburized steel or induction-hardened steel is used.
Bushings
Bushings are positioned among pins and rollers and act as bearings for both the pins and rollers to not transmit the load acquired by the rollers immediately towards the pins once the chain is engaged together with the sprockets. They are really necessary to possess high shock fatigue strength, collapse power and dress in resistance, and normally, carburized steel is used.
Plates
Plates are subject to repeated tension from the chain and at times to significant shocks. They are really required to get substantial tensile power, and especially higher shock strength and fatigue strength. Large tensile steel is made use of for conventional chains 
and heat-treated alloy steel for heavy-duty chains.
T-pins
T-pins avert the outer plates from disengaging from the pins. They’re made from soft steel because pins are usually pressed-in the outer plates and as a result no huge force acts on the T-pins.
