420 Drive Chain
420 Drive Chain Components
Links：Links are the main parts that make up a drive chain, connecting together to form a continuous loop. Each link usually has two outer plates and two inner plates held together by pins. These links give the chain its length and flexibility, allowing it to bend around sprockets.
Rollers：Rollers, situated between the inner plates, help reduce friction when the chain meshes with sprocket teeth. They rotate around the pins, enabling smooth operation and reducing wear on both the chain and the sprockets.
Bushings：ushings are round tube-like parts placed between the pins and rollers. They work like small bearings, helping to cut down friction and wear between the chain’s moving parts. In some types of chains, the bushings are built directly into the inner plates.
Sprockets：Sprockets are wheels with teeth that catch and move the chain, helping to push or pull it forward. How fast and strong the system runs depends on the size of the sprockets and how many teeth they have.
Pins：Pins are the parts that connect the chain links together. They go through the holes in both the inner and outer plates and act as pivot points, letting the chain bend and move smoothly around the sprockets.
