A DK conveyor chain includes a construction, and also the names with the components are stated in the drawing. These parts have functions specified beneath.
Pins
Pins help each of the load acting within the chain along with plates, and when the chain is engaged with all the sprockets, they slide along with bushings as bearings. They are really topic to wear and particularly should have high shear power, bending strength and put on resistance. Hardened and tempered challenging steel, carburized steel, or induction-hardened steel is utilized.
Rollers
Rollers protect the chain from shocks 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 are needed to possess high shock fatigue power, collapse power and wear resistance. Hardened and tempered challenging steel, carburized steel or induction-hardened steel is used.
Bushings
Bushings are positioned amongst pins and rollers and act as bearings for the two the pins and rollers not to transmit the load obtained from the rollers right to your pins when the chain is engaged together with the sprockets. They may be essential to possess high shock fatigue power, collapse power and wear resistance, and usually, carburized steel is made use of.
Plates
Plates are subject to repeated tension with the chain and sometimes to massive shocks. They can be required 
to have higher tensile strength, and especially high shock strength and fatigue power. Higher tensile steel is applied for standard chains and heat-treated alloy steel for heavy-duty chains.
T-pins
T-pins reduce the outer plates from disengaging in the pins. They are really made from soft steel since pins are usually pressed-in the outer plates and hence no big force acts about the T-pins.
