ANSI 80-1 American Standard Heavy-Duty Alloy Steel Roller Chain, for Mining Machinery and Heavy Conveying

The ANSI 80-1 American-standard roller chain is the power core built for heavy industrial transmission, mining machinery, and heavy-load conveying systems. The large 25.4mm pitch combined with alloy steel carburizing and quenching lets it deliver tremendous power even under extremely harsh, dusty, high-shock conditions.

1. Very high tensile strength, built for heavy loads: Compared with small-pitch chains, the 80-1 has an ultimate tensile strength as high as 72.8 kN. The stout pins and thick plates let it handle motor outputs of several hundred kilowatts with ease when driving large crushers and hoists.
2. Alloy steel carburized and hardened, extremely wear-resistant: Pins, bushings, and rollers are all made of quality alloy steel and deep carburized and hardened. Surface hardness is very high, effectively resisting abrasive wear in harsh unlubricated or poorly lubricated environments such as mine dust and muddy water, doubling life.
3. Fatigue- and shock-resistant design: Large-pitch chains experience huge instantaneous impact forces at high-speed operation or heavy-load start-up. The optimized waist-shaped plate holes and precise hole-pin fit eliminate stress concentration and prevent plate fracture and pin shearing.
4. American standard, universal in global heavy industry: Fully conforms to ANSI B29.1 and meshes perfectly with any American-standard No. 80 double- or single-strand heavy-duty sprocket worldwide, the preferred specification for repair and replacement of heavy equipment in North America and internationally.

The "steel backbone" of heavy equipment: High tensile strength and strong wear resistance, built for high-power conveying and heavy-load transmission, completely solving the tendency of small-pitch chains to stretch and break under heavy loads.
A nemesis of harsh conditions: High-hardness alloy steel is unafraid of dust and rain, greatly reducing unplanned downtime on heavy equipment.
Customizable, hassle-free export: Can be cut to any length and supplied with all-steel connecting links, with moisture-proof export packaging in neutral or custom shipping marks.

Mining and quarrying: Main drives of large vibrating screens, jaw crushers, and mining scraper conveyors.
Heavy engineering and construction: Travel and hoisting mechanisms of crawler cranes, concrete batching plants, and large excavators.
Metallurgy and heavy industry: Steel-rolling conveyor lines, large bucket elevators, and heavy-duty winches.
Agriculture and forestry: Large combine harvesters and timber processing conveyor lines.
