A DK conveyor chain has a construction, and the names of the parts are stated while in the drawing. These components have functions specified beneath.
Pins
Pins help all the load acting to the chain together with plates, and once the chain is engaged together with the sprockets, they slide together with bushings as bearings. They’re subject to wear and especially should have large shear strength, bending power and dress in resistance. Hardened and tempered hard steel, carburized steel, or induction-hardened steel is made use of.
Rollers
Rollers secure 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 reduce the resistance when the chain runs on the rail. They can be expected to have large shock fatigue power, collapse power and put on resistance. Hardened and tempered tough steel, carburized steel or induction-hardened steel is employed.
Bushings
Bushings are situated among pins and rollers and act as bearings for each the pins and rollers not to transmit the load received by the rollers right to the pins when the chain is engaged using the sprockets. They may be necessary to have substantial shock fatigue strength, collapse power and put on resistance, and generally, carburized steel is utilized.
Plates
Plates are topic to repeated tension in the chain and often to substantial shocks. They’re necessary to have substantial tensile strength, and particularly substantial shock strength and fatigue strength. Higher tensile 
steel is used for regular chains and heat-treated alloy steel for heavy-duty chains.
T-pins
T-pins protect against the outer plates from disengaging from the pins. They may be made of soft steel due to the fact pins are normally pressed-in the outer plates and thus no huge force acts over the T-pins.
