What components are located between the side plates of common industrial roller chain?

In a common industrial roller chain, the components located between the side plates are the pins, rollers, and bushings.

The pins serve as the main structural element that connects multiple links together, providing the axis around which the rollers can rotate. The rollers are designed to engage with the teeth of sprockets, facilitating the transfer of power and motion as the chain moves. The bushings provide a surface for the rollers to rotate against, reducing friction and wear between the moving parts of the chain.

This combination of pins, rollers, and bushings allows the roller chain to operate smoothly and effectively under various loads, making it a reliable choice in mechanical power transmission systems. Other components like bearings, sprockets, and gears are not located between the side plates of the chain but serve different functions in the larger mechanical system.
