Metal Conveyor Belts Drive Components

Chain links

Chain links are the precision drive-edge components that connect metal conveyor belts to their drive systems. Working together with matching sprockets, they transmit motor torque evenly across the full belt width and maintain consistent belt tension throughout the conveying cycle. PFM Screen supplies a complete range of ISO- and ANSI-standard roller chains, hollow pin chains, and leaf chains in carbon steel, stainless steel, and alloy steel — configured to match any belt width, pitch, and load requirement.

FAQ

Chain links serve as the drive-edge components on all major metal conveyor belt types, including balanced spiral woven, chain link, eye link, compound weave, ladder, flexible rod, and honeycomb (flat wire) belts. Attached along each belt edge, they engage directly with drive sprockets to transmit motion precisely and maintain belt tension under load. Multiple ISO and ANSI pitch series, configuration options, and material grades are available — ensuring a precise match to any existing belt, sprocket, and operating environment.

Chain links

Chain links are available in carbon steel (standard industrial duty), stainless steel SS304 or SS316 (food processing and corrosive environments), and alloy steel (heavy-load or high-temperature applications). Pitch, roller diameter, inner plate width, strand count, and attachment type are all specified to match your existing conveyor belt and drive components exactly — ensuring drop-in replacement without modification to your conveyor frame or sprocket assembly.

Material Availability

Chain links are available in the following material grades:
Carbon steel — standard duty for dry, non-corrosive general industrial environments.
Stainless steel SS304 — food-grade specification for food processing, baking, frying, freezing, and standard CIP washdown environments.
Stainless steel SS316 — marine-grade with added molybdenum; superior resistance to chlorides and aggressive sanitising chemicals. Recommended for seafood, dairy, and meat processing.
Alloy steel — for heavy-duty or elevated-temperature applications requiring higher tensile strength than carbon steel.
Other specifications available on request.
