Hollow Pin Conveyor Chains (FVC Series) for Custom Attachments | Donghua

Donghua's hollow pin conveyor chains (FVC Series) are engineered to solve one of the most common challenges in custom conveying: the need to mount attachments, flights, or specialized tooling directly to the chain. The hollow pin design provides a clean, secure attachment point, allowing you to build the exact conveying solution your application demands. As a leading global chain manufacturer since 1991, our FVC series chains are precision-engineered for reliability and flexibility.

Hollow Pin Technology: How It Enables Custom Conveying

Unlike standard roller chains, hollow pin chains feature pins that are tubular rather than solid. This design offers a distinct advantage: the hollow pin creates a perfect mounting point for custom attachments, flights, or crossbars. Key technical features include:

Attachment Versatility: Easily integrate custom fixtures, pushers, carriers, or sensors directly into the chain.
Standard Compatibility: Built on ISO 606 roller chain dimensions, so they are compatible with standard sprockets.
Pair-Matched for Precision: For applications requiring parallel running (common in double-strand conveying), we supply chains in matched pairs to ensure exact alignment and smooth operation.
High-Quality Components: Chain plates are manufactured using fine blanking and ball stamping for high contact rates. Hollow pins are made from seamless precision steel tubes for increased precision and wear resistance. Rollers are case-hardened for durability.
