A DK conveyor chain features a framework, plus the names from the elements are stated in the drawing. These components have functions specified below.
Pins
Pins assistance each of the load acting to the chain together with plates, and when the chain is engaged using the sprockets, they slide along with bushings as bearings. They may be subject to wear and particularly must have higher shear strength, bending strength and dress in resistance. Hardened and tempered challenging steel, carburized steel, or induction-hardened steel is made use of.
Rollers
Rollers secure the chain from shocks together 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 may be expected to get substantial 
shock fatigue power, collapse strength and put on resistance. Hardened and tempered difficult steel, carburized steel or induction-hardened steel is used.
Bushings
Bushings are positioned involving pins and rollers and act as bearings for both the pins and rollers to not transmit the load acquired by the rollers straight on the pins once the chain is engaged with all the sprockets. They may be demanded to possess higher shock fatigue power, collapse power and dress in resistance, and on the whole, carburized steel is applied.
Plates
Plates are subject to repeated stress of your chain and from time to time to large shocks. They are essential to get higher tensile strength, and especially higher shock power and fatigue strength. Higher tensile steel is utilized for normal chains and heat-treated alloy steel for heavy-duty chains.
T-pins
T-pins reduce the outer plates from disengaging through the pins. They’re made from soft steel considering the fact that pins are typically pressed-in the outer plates and hence no massive force acts within the T-pins.
