Side bow chains are often used in conveyor systems that follow curved paths or in drag applications. These chains have the ability to move along curves with different radii. The chain's rotating ability allows it to move smoothly through various curves. This flexibility enables the chain to follow the curves required by the application.

In such chains, the pin diameter can be reduced in order to overcome bends more easily. Additionally, special designs such as conical pins or double conical bushings can be used to ensure that the chain moves balancedly and effectively in bends. These features ensure that side spring chains can operate reliably along complex and inclined paths.
