Rows of unfinished roller chain are laid across a workbench while a technician installs the remaining outer plates by hand. A small positioning tool keeps each plate aligned with the two exposed pins before it is secured into place.
Once aligned, the tool transfers the force of each hammer strike onto the plate, pressing it evenly down onto the pins. The process is repeated along the chain, completing one connection after another while maintaining consistent positioning between the components.
Roller chains depend on accurately assembled pins, plates, bushings, and rollers to articulate smoothly while transmitting mechanical power. This basic design is used throughout machinery, conveyors, motorcycles, agricultural equipment, and countless other mechanical systems.
