About 12B Hollow Pin Roller Chain

12B Hollow Pin Roller Chain is manufactured following ISO 606 metric standard. Different from standard solid‑pin chains, it adopts hollow pin structure, allowing customers to install cross‑rods, attachments and accessories quickly without disassembling the whole chain. Made of high‑grade carbon steel, this chain has good tensile strength and wear‑resistant property. It is widely used for conveyor systems, food processing machinery, packaging and automated production lines. Custom surface treatments such as zinc‑plating are available.
