A DK conveyor chain features a framework, along with the names with the components are stated within the drawing. These parts have functions specified under.
Pins
Pins assistance every one of the load acting over the chain together with plates, and once the chain is engaged using the sprockets, they slide along with bushings as bearings. They can be topic to 
dress in and especially should have higher shear strength, bending strength and wear resistance. Hardened and tempered hard steel, carburized steel, or induction-hardened steel is utilised.
Rollers
Rollers guard the chain from shocks with all the sprockets, and once the chain is engaged using the sprockets, the rollers bend the chain smoothly and act to lessen the resistance once the chain runs on a rail. They can be demanded to possess large shock fatigue power, collapse power and put on resistance. Hardened and tempered hard steel, carburized steel or induction-hardened steel is utilized.
Bushings
Bushings are located involving pins and rollers and act as bearings for the two the pins and rollers not to transmit the load obtained by the rollers immediately to the pins when the chain is engaged together with the sprockets. They may be essential to possess substantial shock fatigue power, collapse strength and dress in resistance, and usually, carburized steel is used.
Plates
Plates are topic to repeated tension in the chain and from time to time to significant shocks. They are really required to possess higher tensile strength, and especially large shock power and fatigue strength. Higher tensile steel is used for typical 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 can be manufactured from soft steel given that pins are normally pressed-in the outer plates and consequently no large force acts about the T-pins.
