What Is a Simple (Simplex) Roller Chain?
Simple roller chain — also called simplex roller chain — is a single-strand drive chain consisting of alternating inner and outer link plates, hardened steel pins, precision bushings, and free-rotating rollers. It is the most widely produced and stocked roller chain configuration in global industry, covering pitches from 12.70 mm (08B-1) through to 76.2 mm (48B-1) under ISO 606, and a matching range under ANSI B29.1. The simplex strand is the base unit from which duplex (two-strand) and triplex (three-strand) assemblies are built when higher load capacity is required without increasing pitch.
The working principle is unchanged since Hans Renold’s 1879 patent: each sprocket tooth engages a roller, transmitting torque through the pin-bushing interface. The roller rotates freely on the bushing, converting sliding friction into rolling contact — which is why correctly lubricated roller chain drives achieve 97–99% mechanical efficiency, outperforming V-belt alternatives on most continuous-duty cycles.
Ever Power simple roller chains are manufactured in carbon steel and stainless steel to ISO 606:2015 and ASME B29.1-2011. Every production batch is proof-load tested to 50% of published minimum tensile strength before despatch. Full dimensional inspection certificates and EN 10204 3.1 material mill certificates are supplied as standard on food-grade and regulated-environment orders.

Note: ISO 08B-1 and ANSI 40-1 share the same 12.70 mm pitch but have different roller diameters (8.51 mm vs 7.92 mm) and are not interchangeable on the same sprocket. Always match chain and sprocket to the same standard.

Core Technical Advantages
97–99% Mechanical Efficiency
Rolling contact replaces sliding friction. Under correctly lubricated conditions roller chain consistently outperforms V-belt drives on high-torque continuous duty — even a 1% efficiency gain translates to measurable energy savings at scale.
Geen slip — Exacte snelheidsverhouding
Positive tooth engagement on every revolution. Speed ratio is exact and constant — essential for packaging lines, printing machinery, and multi-axis timing applications where synchronisation must hold across a full production shift.
−40 °C to +150 °C Operating Range
Standard carbon steel performs reliably across this range; high-temperature alloy variants extend to +300 °C. Tolerates oil, dust, and moderate chemical contamination — environments that rapidly degrade rubber belts or damage precision gearbox seals.
Predictable, Measurable Wear
Chain elongation is measurable with a simple ruler — replacement can be scheduled as planned maintenance rather than emergency response. Well-maintained drives achieve 15,000–25,000 hours service life before replacement is required.
Simple Field Maintenance
Chain replacement requires hand tools and no specialist knowledge. No proprietary service tooling, no dealer callout — a compelling total-cost argument for UK manufacturing operations managing tight maintenance budgets.
Simplex / Duplex / Triplex
Load capacity scales by adding strands without changing pitch or sprocket tooth count. Attachment plates, extended pins, hollow-pin variants, self-lubricating bushings, and stainless steel all available across the standard range.

Aggregate processing · ANSI 120-1 heavy series
Chain replacement intervals were running at 11 months — well below the 18-month target built into the maintenance budget. After trialling the Ever Power 120HSP high-strength series in parallel with standard 120-1 chain on an adjacent drive, the HSP chain showed 38% less elongation at the 14-month mark. The trial was extended to all conveyor drives in early 2024. Replacement intervals moved to 19–21 months, recovering the original design target and reducing annual chain procurement spend by approximately £22,000 across the site.
“We had written off hitting our eighteen-month change interval. The Ever Power HSP chain recovered it at nineteen months without any change to our lubrication regime. The elongation figures were the best we have seen on any chain across this site.”
