ANSI 80 Roller Chain — Heavy Duty
80-1 / 80-2 / 80H-1 • 1″ Pitch • 58–116 kN • ASME B29.1
ANSI 80 roller chain is the standard heavy-duty chain for industrial drives requiring high tensile strength at moderate-to-low speeds. With a 1 inch (25.40 mm) pitch and a minimum tensile strength of 58.0 kN in the 80-1 simplex configuration, the 80 series covers steel plant conveyor drives, heavy aggregate handling, timber processing, and mining auxiliary equipment. The 80H-1 heavy series uses a larger pin diameter (9.53 mm vs standard 7.92 mm) for significantly higher fatigue resistance under shock loading — the specification most commonly requested by quarrying and cement plant operators across the UK’s industrial regions including Derbyshire, the Welsh valleys, and Yorkshire.

| Номер цепи. | Ряд | Шаг (мм) | Диаметр ролика (мм) | Внутренняя ширина (мм) | Диаметр штифта (мм) | Min. Tensile (kN) | Вес (кг/м) |
|---|---|---|---|---|---|---|---|
| 80-1 | Стандарт | 25.40 | 15.88 | 15.75 | 7.92 | 58.0 | 2.60 |
| 80-2 | Duplex | 25.40 | 15.88 | 15.75 | 7.92 | 116.0 | 5.10 |
| 80H-1 | Heavy | 25.40 | 15.88 | 15.75 | 9.53 | 67.0 | 3.10 |
Per ASME B29.1-2011. 80H-1 heavy series uses larger pin diameter (9.53 mm vs standard 7.92 mm) for higher fatigue resistance under shock loading. ISO 16A-1 equivalent — inner width 15.88 mm differs slightly.
80-1 Standard — Choose when:
Load is steady or moderately variable • Speed is above 500 RPM • Budget is the primary constraint • Standard maintenance intervals are acceptable
80H-1 Heavy — Choose when:
Shock loading is frequent • Speed is below 200 RPM under high torque • Extended replacement intervals are the priority • Quarrying, aggregate, or steel plant environment
Material and Construction — Heavy Duty Focus
Alloy Steel Pins
20CrMnTi alloy steel standard on 80 series. Chromium + manganese supports deeper case hardening and tougher core than SAE 1045 at this pin diameter. Surface 58–64 HRC, core 35–45 HRC.
Heavy-Series Side Plates
80H-1 uses thicker plate stock with tighter pitch hole tolerances vs standard 80-1. Maintains load distribution across the plate under sustained high-load cycles. Cotter-pin connecting links standard.
QC & Certification
100% proof-load tested at 50% min. tensile. Full lot traceability to mill cert. EN 10204 2.1 standard; 3.1 mill cert for regulated or safety-critical applications.
Typical Applications — ANSI 80 Heavy Duty
Ordering and Supply
Stock
3 m and 5 m lengths • 80-1, 80-2, 80H-1 • Cotter-pin connecting links in stock
Matched pairs
Duplex matched-pair sets with strand-to-strand pitch variation below 0.05 mm per 30 pitches — preventing uneven fatigue in multi-strand drives
Consignment stock
For critical production sites — bonded inventory at UK warehouse eliminates lead time risk on emergency replacements
