A DK conveyor chain includes 
a structure, as well as the names from the parts are stated from the drawing. These parts have functions specified under.
Pins
Pins help each of the load acting within the chain along with plates, and when the chain is engaged with all the sprockets, they slide together with bushings as bearings. These are topic to dress in and particularly must have large shear strength, bending power and dress in resistance. Hardened and tempered hard steel, carburized steel, or induction-hardened steel is used.
Rollers
Rollers secure the chain from shocks with all the sprockets, and once the chain is engaged with the sprockets, the rollers bend the chain smoothly and act to reduce the resistance once the chain runs on the rail. They’re demanded to have large shock fatigue power, collapse strength and dress in resistance. Hardened and tempered hard steel, carburized steel or induction-hardened steel is utilised.
Bushings
Bushings are located concerning pins and rollers and act as bearings for the two the pins and rollers to not transmit the load received through the rollers straight to your pins when the chain is engaged using the sprockets. They may be essential to possess substantial shock fatigue strength, collapse strength and put on resistance, and on the whole, carburized steel is utilised.
Plates
Plates are subject to repeated stress of your chain and occasionally to massive shocks. They can be needed to get high tensile strength, and especially high shock power and fatigue power. Substantial tensile steel is employed for typical 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 are made of soft steel considering the fact that pins are typically pressed-in the outer plates and consequently no massive force acts around the T-pins.
