A DK conveyor chain has a construction, as well as the names on the parts are stated from the drawing. These elements have functions specified below.
Pins
Pins assistance all of the load acting over the chain along with plates, and once the chain is engaged with the sprockets, they slide along with bushings as bearings. These are topic to wear and particularly ought to have large shear strength, bending power and wear resistance. Hardened and tempered difficult steel, carburized steel, or induction-hardened steel is applied.
Rollers
Rollers safeguard the chain from shocks with all the sprockets, and when the chain is engaged with all the sprockets, the rollers bend the chain smoothly and act to lessen the resistance once the chain runs on the rail. They can be required to get higher shock fatigue power, collapse strength and put on resistance. Hardened and tempered difficult steel, carburized steel or induction-hardened steel is utilised.
Bushings
Bushings are positioned concerning pins and rollers and act as bearings for both the pins and rollers not to transmit the load obtained through the rollers immediately to the pins when the chain is engaged together with the sprockets. They’re essential to possess higher shock fatigue power, collapse strength and wear resistance, and in general, carburized steel is used.
Plates
Plates are topic to repeated stress of your chain and at times to substantial shocks. They can be demanded to 
have high tensile power, and especially large shock power and fatigue strength. Substantial tensile steel is made use of 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 generally pressed-in the outer plates and so no massive force acts on the T-pins.
