Description
1775 Gapless Sideflex Run Single Hinge Chain
High-performance plastic modular chain engineered for smooth radius conveying, gapless product support, and continuous operation in demanding UK industrial environments.
The 1775 Gapless Sideflex Run Single Hinge Chain represents a refined solution for conveyor systems that demand both lateral flexibility and an unbroken belt surface. With a pitch of 25 mm and a chain width of 70 mm, this belt is purpose-built for applications where product orientation must remain stable throughout curved conveyor paths. The gapless design eliminates the small-item drop-through risk common on standard modular belts, making it a preferred choice across UK food manufacturing, pharmaceutical packaging, and precision light assembly operations. Unlike many conventional sideflex chains, the single hinge construction reduces mechanical complexity while maintaining a minimum sideflex radius of 150 mm — tight enough to navigate most compact conveyor footprints found in space-sensitive UK production halls.
The chain is constructed from XLG engineering-grade plastic, combining low weight at 1.05 kg/m with a robust working load capacity of 1000 N at 21°C. Operating comfortably across a temperature range of 4–64°C in both dry and wet conditions, it suits washdown environments without compromising mechanical integrity. Whether installed on a new conveyor or retrofitted to an existing system, the 1775 sideflex single hinge chain is dimensionally consistent and straightforward to assemble without specialist tooling.

How It Works: Chain Mechanics & Material Science
The single hinge design is the mechanical heart of the 1775 chain. Each module connects via a single transverse hinge rod that allows the belt to flex laterally as it navigates curved conveyor paths. Because only one hinge point per module is engaged during lateral movement, friction and wear are substantially lower than in double-hinge alternatives. The result is a longer service life and more predictable tension behaviour across the full belt width — a critical consideration when running at sustained production speeds on UK processing lines operating multiple shifts per day.
The XLG material chosen for this chain is an engineering-grade polyacetal compound formulated for low friction coefficients against stainless steel wearstrips, high dimensional stability across the working temperature range, and resistance to the dilute acids, alkalis, and sanitising agents used in UK food and pharmaceutical production environments. Unlike standard acetal, XLG retains its mechanical properties at the upper boundary of the 64°C working temperature, meaning hot-fill and pasteurisation-adjacent conveyor sections remain within operational parameters without needing a higher-cost belt solution.
The gapless surface geometry ensures that even small, delicate, or irregular products — such as pouches, cartons, or components with narrow contact footprints — travel without risk of tipping or drop-through. This matters enormously in high-speed UK packaging environments where product integrity directly affects line efficiency and downstream inspection accuracy.
Why UK Engineers Specify This Chain
True Gapless Surface
No product drop-through. Ideal for small parts, sachets, cartons, and anything with limited contact geometry on curved runs.
Compact Sideflex Radius
150 mm minimum sideflex radius enables tight conveyor curves, reducing floor space requirements on constrained UK production sites.
Washdown Compatible
XLG material resists standard cleaning chemicals. Full wet and dry temperature range of 4–64°C covers chilled and ambient UK environments.
Low Installation Complexity
Single hinge construction simplifies assembly, reduces the number of spare parts on site, and cuts scheduled maintenance time significantly.
1000 N Working Load
Substantial load capacity supports high-throughput conveyor lines without premature fatigue, even under sustained multi-shift production schedules.
Lightweight at 1.05 kg/m
Lower belt weight reduces motor energy consumption and drive component wear — a measurable efficiency gain over steel alternatives on long conveyor circuits.
Application Scenarios Across UK Industry
The 1775 sideflex single hinge chain finds its natural home in any conveyor system that must change direction horizontally while keeping products firmly supported and correctly oriented. In UK food manufacturing — particularly in bakery, dairy, ready meals, and confectionery sectors — curved conveyors link multiple processing zones within tight factory footprints. The gapless surface ensures even lightweight packaging maintains contact across lateral transition points where belt tension shifts and surface geometry can cause instability on conventional chains.
Pharmaceutical and nutraceutical lines across the Midlands and the South East have adopted this chain specifically for its dimensional consistency and chemical resistance. When handling blister packs, bottle trays, or folded cartons through radius sections feeding labelling or inspection stations, the reliable 150 mm sideflex radius ensures product positioning is preserved frame by frame. Logistics and e-commerce fulfilment centres operating sorter systems also benefit from the single hinge design’s predictable tension behaviour under varying load profiles — critical in facilities where line speeds fluctuate significantly throughout the working day.
Light assembly and electronics component handling operations represent a third strong use case. Here, the gapless surface prevents small components from becoming lodged between belt modules — a common cause of production stoppages and quality escapes on conventional modular belts. The low running friction of XLG against standard wearstrip profiles also reduces the thermal load on these often-compact conveyors, keeping drive motor temperatures within acceptable ranges.
| Industry / Sector | Typical UK Application | Key Benefit |
|---|---|---|
| Food & Beverage | Bakery, dairy, ready meals radius conveyors | Gapless surface, washdown safe |
| Pharmaceuticals | Blister pack and carton handling, radius turns | Chemical resistance, product stability |
| Logistics / Fulfilment | Sortation and merging conveyor systems | Predictable tension, low maintenance |
| Light Assembly / Electronics | Component handling on curved index lines | No drop-through, low friction |
| Packaging | Infeed to labelling, wrapping, inspection | Consistent product positioning |
Customer Success: UK Food Manufacturer Cuts Belt Change Frequency by 40%
Case Study — Midlands-based ready meals manufacturer, 2024
A mid-sized ready meals producer operating two 24/5 production lines near Coventry was experiencing excessive downtime due to premature wear on their existing sideflex belt. The conveyor system featured three 90-degree radius turns feeding a high-speed portioning station, and their previous belt supplier could not provide a consistent supply of correctly dimensioned replacement sections at acceptable lead times.
Following a technical review, the production engineering team selected the 1775 Gapless Sideflex Run Single Hinge Chain as a direct replacement. The 150 mm sideflex radius matched the existing conveyor geometry without structural modification. Within the first six months of operation, belt replacement frequency dropped by 40%, and the maintenance team reported a significant reduction in manual re-tensioning between shifts. The washdown compatibility of the XLG material also meant cleaning cycles could proceed on schedule without the chain requiring drying time before restart — a genuine operational improvement that translated into measurable uptime gains across both lines.
“We’ve been running this chain on our curved conveyor sections for eight months now without a single unplanned stoppage related to the belt. The gapless surface has eliminated the small-pouch jam issue we had repeatedly with our old belt. Excellent product.”
“The technical support from the supplier team was genuinely impressive. They helped us confirm the sideflex radius compatibility before we ordered. Delivery was fast, and the belt fitted perfectly first time. We’ve since standardised on this chain across our pharmaceutical packaging lines.”
“We operate a complex sortation system in our fulfilment centre and the 1775 chain handles the variable load profiles without complaint. The lightweight construction has also noticeably reduced the running temperature of our drive motors. Solid engineering at a competitive price.”
