A DK conveyor chain includes a structure, as well as names in the elements 
are stated in the drawing. These parts have functions specified below.
Pins
Pins support the many load acting on the chain together with plates, and when the chain is engaged with the sprockets, they slide along with bushings as bearings. These are subject to put on and particularly should have large shear strength, bending power and wear resistance. Hardened and tempered difficult steel, carburized steel, or induction-hardened steel is used.
Rollers
Rollers secure the chain from shocks together with 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 a rail. They can be essential to get high shock fatigue strength, collapse power and put on resistance. Hardened and tempered hard steel, carburized steel or induction-hardened steel is utilized.
Bushings
Bushings are found among pins and rollers and act as bearings for the two the pins and rollers not to transmit the load obtained through the rollers right on the pins when the chain is engaged using the sprockets. They’re needed to possess high shock fatigue power, collapse strength and put on resistance, and in general, carburized steel is made use of.
Plates
Plates are subject to repeated tension from the chain and sometimes to massive shocks. They’re expected to possess higher tensile strength, and particularly higher shock strength and fatigue strength. Large tensile steel is utilized for regular chains and heat-treated alloy steel for heavy-duty chains.
T-pins
T-pins prevent the outer plates from disengaging through the pins. They may be manufactured from soft steel since pins are usually pressed-in the outer plates and so no big force acts over the T-pins.
