A DK conveyor chain has a construction, as well as names in the components are stated within the drawing. These parts have functions specified beneath.
Pins
Pins support all of the load acting over the chain together with plates, and when the chain is engaged with all the sprockets, they slide together with bushings as bearings. They are really subject to wear and especially should have large shear power, bending power and put on resistance. Hardened and tempered hard steel, carburized steel, or induction-hardened steel is applied.
Rollers
Rollers protect the chain from shocks with the sprockets, and when the chain is engaged together with the sprockets, the rollers bend the chain smoothly and act to lessen the resistance once the chain runs on the rail. They’re demanded to have higher shock fatigue power, collapse strength and wear resistance. Hardened and tempered tough steel, carburized steel or induction-hardened steel is made use of.
Bushings
Bushings are located amongst pins and rollers and act as bearings for each the pins and rollers not to transmit the load obtained from the rollers directly for the pins when the chain is engaged with all the sprockets. They are really necessary to get high shock fatigue strength, collapse strength and wear resistance, and normally, carburized steel is utilized.
Plates
Plates are subject to repeated tension in the chain and often to significant shocks. They’re necessary to possess large tensile strength, and particularly large shock power and fatigue strength. Higher tensile steel is applied for conventional chains and heat-treated alloy steel for heavy-duty chains.
T-pins
T-pins avert the outer plates from disengaging in the pins. They are made of soft steel 
since pins are usually pressed-in the outer plates and so no large force acts around the T-pins.
