A DK conveyor chain features a framework, plus the names of your parts are stated inside the drawing. These elements have functions specified beneath.
Pins
Pins assistance every one 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're subject to put on and particularly need to have substantial shear strength, bending strength and dress in resistance. Hardened and tempered difficult steel, carburized steel, or induction-hardened steel is employed.
Rollers
Rollers secure the chain from shocks using the sprockets, and once the chain is engaged together with the sprockets, the rollers bend the chain smoothly and act to reduce the resistance when the chain runs on the rail. They are required to possess substantial shock fatigue strength, collapse power and dress in resistance. Hardened and tempered hard steel, carburized steel or induction-hardened steel is used.
Bushings
Bushings are situated concerning pins and rollers and act as bearings for each the pins 
and rollers to not transmit the load obtained through the rollers immediately to your pins once the chain is engaged together with the sprockets. They are really demanded to have higher shock fatigue power, collapse power and dress in resistance, and in general, carburized steel is utilised.
Plates
Plates are subject to repeated stress of the chain and often to substantial shocks. They are needed to have large tensile power, and particularly large shock power and fatigue strength. Large 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 in the pins. These are made from soft steel considering that pins are normally pressed-in the outer plates and so no massive force acts on the T-pins.
