About 20B-3 Roller Chain

20B‑3 triple‑strand roller chain is manufactured to ISO metric standard. Made of high‑quality alloy steel, it delivers excellent tensile strength, wear resistance and stable long‑time operation. Its three‑row structure provides higher power‑transmission capacity than single and double‑strand chains. Precision‑machined components ensure smooth meshing with matching sprockets. Widely used in heavy‑duty conveyors, agricultural machinery, mining and industrial‑driving equipment. We can offer surface treatment and custom‑made services to meet your special working‑condition requirements.
