A DK conveyor chain has a structure, as well as the names of the components are stated within the drawing. These elements have functions specified beneath.
Pins
Pins help each of the load acting on the chain together with plates, and when the chain is engaged together with the sprockets, they slide together with bushings as bearings. They can be topic to put on and particularly will have to have substantial shear strength, bending power and wear resistance. Hardened and tempered tough steel, carburized steel, or induction-hardened steel is applied.
Rollers
Rollers secure the chain from shocks with the sprockets, and once 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 are really necessary to get large shock 
fatigue power, collapse power and wear resistance. Hardened and tempered hard steel, carburized steel or induction-hardened steel is made use of.
Bushings
Bushings are located concerning pins and rollers and act as bearings for both the pins and rollers to not transmit the load acquired through the rollers right to the pins once the chain is engaged with all the sprockets. They are required to get substantial shock fatigue strength, collapse strength and wear resistance, and on the whole, carburized steel is applied.
Plates
Plates are topic to repeated stress with the chain and at times to massive shocks. These are required to possess large tensile power, and particularly large shock power and fatigue strength. Large tensile steel is utilized for standard 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 are really manufactured from soft steel considering that pins are frequently pressed-in the outer plates and thus no substantial force acts to the T-pins.
