A DK conveyor chain features a construction, plus the names from the parts are stated during the drawing. These parts have functions specified under.
Pins
Pins support all of the load acting to the chain along with plates, and once the chain is engaged with the sprockets, they slide together with bushings as bearings. They can be topic to wear and particularly must have substantial shear power, bending strength and put on resistance. Hardened and tempered hard steel, carburized steel, or induction-hardened steel is employed.
Rollers
Rollers defend the chain from shocks using the sprockets, and when the chain is engaged using the sprockets, the rollers bend the chain smoothly and act to reduce the resistance when the chain runs on a rail. They may be necessary to possess higher shock fatigue power, collapse strength and wear resistance. Hardened and tempered hard steel, carburized steel or induction-hardened steel is employed.
Bushings
Bushings are situated involving pins and rollers and act as bearings for each the pins and rollers not to transmit the load acquired through the rollers straight for the pins when the chain is engaged with the sprockets. They can be required 
to get large shock fatigue strength, collapse strength and wear resistance, and generally, carburized steel is applied.
Plates
Plates are subject to repeated stress in the chain and from time to time to substantial shocks. They are essential to have substantial tensile power, and especially higher shock power and fatigue strength. Substantial tensile steel is used for normal chains and heat-treated alloy steel for heavy-duty chains.
T-pins
T-pins avoid the outer plates from disengaging through the pins. They are really made from soft steel considering the fact that pins are generally pressed-in the outer plates and therefore no large force acts about the T-pins.
