Inner and Outer Links:Roller chains usually have 2 sorts of links: internal links (roller links) and external web links (pin web links).
Rollers:Short, cylindrical rollers are a key component of the internal web links, promoting smooth involvement with sprockets and lowering rubbing.
Bushings (Sleeves):Bushings or sleeves are used to sustain the rollers within the internal web links.
Pins:Pins hold the outer links together and pass through the bushings of the internal web links.
Sprocket Engagement:The rollers of the chain engage with the teeth of a sprocket to send rotational movement.
