#120-4 four-strand roller chain strictly follows ANSI standard specifications. Built with thick side plates, solid pins and precision-machined rollers, this multi-strand chain boasts ultra-high tensile strength, excellent load-bearing capacity and superior fatigue resistance for heavy-duty transmission.
Subject to standardized heat treatment and anti-wear surface processing, it runs smoothly with low elongation under continuous high-load operation. Ideal for large conveyors, mining equipment, heavy machinery and bulk material transportation systems. Custom versions including stainless steel, hollow pins and special attachments are available to meet customized assembly and harsh working environment demands.
