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.

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

Seosterästapit

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

Teräs ja metallit

Secondary conveyor and handling drives in Sheffield, Rotherham, and Scunthorpe steel facilities • 80H-1 preferred for continuous-duty runs

Quarrying & Aggregates

Primary feed conveyors in limestone, granite, and recycled aggregate operations • 80H-1 with 2,000 hr planned replacement intervals

Maatalouskoneet

Large combine harvester straw walkers, large square balers, forage harvester main drives built to North American ANSI specification

Timber & Cement

Timber handling systems and cement plant bucket elevator drives • Environments where shock loading from uneven feed material is an ongoing condition

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
