A DK conveyor chain has a structure, and the names on the components are stated from the drawing. These elements have functions specified below.
Pins
Pins support each of the load acting around the chain together with plates, and when the chain is engaged with all 
the sprockets, they slide together with bushings as bearings. They’re topic to dress in and particularly ought to have substantial shear strength, bending power and put on resistance. Hardened and tempered challenging steel, carburized steel, or induction-hardened steel is utilized.
Rollers
Rollers safeguard the chain from shocks using the sprockets, and when the chain is engaged with the sprockets, the rollers bend the chain smoothly and act to lessen the resistance when the chain runs on the rail. They can be expected to get substantial shock fatigue power, collapse strength and wear resistance. Hardened and tempered hard steel, carburized steel or induction-hardened steel is applied.
Bushings
Bushings are found among pins and rollers and act as bearings for both the pins and rollers to not transmit the load acquired from the rollers immediately to the pins when the chain is engaged together with the sprockets. They can be necessary to possess higher shock fatigue power, collapse strength and wear resistance, and generally, carburized steel is made use of.
Plates
Plates are subject to repeated tension in the chain and at times to massive shocks. They may be demanded to possess high tensile power, and particularly higher shock power and fatigue power. Higher tensile steel is applied for conventional chains and heat-treated alloy steel for heavy-duty chains.
T-pins
T-pins avert the outer plates from disengaging from your pins. They’re made of soft steel considering that pins are frequently pressed-in the outer plates and therefore no massive force acts on the T-pins.
