What Is the 820 Single Row Sideflex Run Single Hinge Chain?<\/h2>\n
\n

\"820The 820 Single Row Sideflex Run Single Hinge Chain is a high-performance modular plastic conveyor chain engineered specifically for curved and sideflex conveyor layouts. Unlike conventional straight-running chains, this design incorporates a single-hinge pivot architecture that allows the belt to navigate horizontal bends smoothly \u2014 without sacrificing load integrity or surface contact. With a pitch of 38.1 mm and a minimum backflex radius of just 40 mm, it handles tight conveyor curves that would defeat conventional flat-top chains. The 820 series is a widely adopted standard in UK manufacturing facilities, food production lines, and packaging plants where layout space is limited and product transfer must remain stable throughout every curve and transition.<\/p>\n

Built from XLG (Extra Low Gravity polypropylene) or PS (polystyrene-based compound), the chain combines chemical resistance with dimensional stability under both dry and wet working conditions. Its open-hinge construction promotes thorough drainage and hygiene cleaning \u2014 a critical factor for UK food manufacturers operating under Food Standards Agency (FSA) guidelines. The maximum working load of 1,230 N at 21\u00b0C makes it suitable for medium-duty product lines, from poultry processing conveyors in Yorkshire to bottling lines in the Midlands.<\/p>\n<\/div>\n<\/div>\n

Materials, Working Principle & Application Scenarios<\/h2>\n
\n
\n

\u25b6 How It Works<\/h3>\n

Each module of the 820 sideflex hinge chain is connected through a single transverse hinge rod. When the chain enters a horizontal curve, individual modules pivot slightly relative to each other around this rod, enabling the belt to track along the inside radius of the curve without binding. The single-hinge design concentrates articulation at a defined pivot point, which distributes wear evenly and ensures consistent tracking performance throughout the chain’s service life. This is fundamentally different from straight-running chains, where lateral movement is constrained \u2014 here, the geometry is deliberately designed to encourage controlled sideways flex while maintaining longitudinal tension and surface planarity.<\/p>\n<\/div>\n

\n

\u25b6 Material Science<\/h3>\n

The XLG grade is an engineering polypropylene compound with enhanced impact resistance and low friction coefficient. It performs well under refrigeration conditions (4\u00b0C minimum) without becoming brittle \u2014 ideal for chilled dairy or meat conveyor lines in UK cold-storage facilities. The PS variant offers greater rigidity and surface hardness, making it the preferred choice for dry goods packaging environments where belt deflection under load must be minimised. Both materials are non-toxic, non-porous, and free of heavy metal additives \u2014 supporting compliance with UK food contact material regulations derived from EU Regulation 10\/2011, which remains referenced under UK retained law.<\/p>\n<\/div>\n

\n

\u25b6 Where It’s Used<\/h3>\n

The 820 sideflex chain is most commonly deployed in food & beverage processing plants, specifically in wet zones like fish filleting lines, poultry washdown areas, and fruit and vegetable washing conveyors. In the pharmaceutical sector, its clean-surface profile supports tablet and capsule transfer on curved sorter belts. Packaging facilities across the UK Midlands and North England use it to route product streams around tight corner transfers in space-constrained layouts. It also sees regular use in baking and confectionery environments where grease resistance and thermal stability between 4\u00b0C and 64\u00b0C are non-negotiable production requirements.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Customer Success: Poultry Processing Plant, Yorkshire, UK<\/h2>\n
\n

Background: A mid-sized poultry processing facility in Harrogate, North Yorkshire, was running a 12-year-old stainless steel slat chain on its wet-zone inspection conveyor. The existing setup required weekly lubrication, experienced frequent jam events at its two 90-degree bends, and could not be wet-cleaned in place due to the chain design. Downtime from jams and cleaning averaged 4.5 hours per week.<\/p>\n

Solution: The plant’s maintenance manager sourced 820-K450 sideflex hinge chains in XLG material across two conveyor runs. The 114.8 mm chain width matched existing guide rail spacing, eliminating the need for frame modification. Installation was completed over a single weekend shutdown \u2014 significantly less disruption than a full frame replacement would have required. The 40 mm minimum backflex radius easily accommodated both existing corner transfers.<\/p>\n

Outcome: Over the following three months, unplanned conveyor downtime dropped by approximately 80%. CIP cleaning time per shift fell from 35 minutes to under 12 minutes. The XLG material’s lubrication-free running eliminated the previous contamination risk from chain lubricant migrating onto the product surface \u2014 a factor that had previously generated quality audit observations. The site has since retrofitted a third conveyor run with the same chain specification.<\/p>\n<\/div>\n

\n
\n
Q: What is the minimum bend radius for the 820 sideflex chain used in a UK food processing conveyor application?<\/div>\n
\n

The 820 series sideflex hinge chain has a minimum backflex radius of 40 mm across all three width variants (K325, K450, K600). This applies consistently in both dry and wet operating environments within the 4\u00b0C to 64\u00b0C working temperature range \u2014 well suited to the curve radii found in most UK food processing conveyor layouts.<\/p>\n<\/div>\n<\/div>\n

\n
Q: How much does the 820 sideflex plastic modular chain cost and where can I get a price quote for a UK supplier?<\/div>\n
\n

Pricing for the 820 sideflex hinge chain depends on the belt type (K325, K450, or K600), material selection (XLG or PS), and total chain length required. To receive an accurate quote tailored to your UK conveyor project, please email sales@plastic-modular-belt.com<\/a> with your chain width, quantity, and any custom requirements. We respond to all enquiries within one working day.<\/p>\n<\/div>\n<\/div>\n

\n
Q: Which material should I choose between XLG and PS for a wet-zone poultry conveyor in the United Kingdom?<\/div>\n
\n

For wet-zone poultry processing environments in UK facilities, XLG polypropylene is the recommended choice. It retains impact resistance and flexibility at the lower end of the 4\u00b0C to 64\u00b0C working temperature range, supports CIP washdown cleaning routines, and meets food contact material standards applicable in the UK. The PS variant is better suited to dry ambient environments such as dry biscuit or packaging lines.<\/p>\n<\/div>\n<\/div>\n

\n
Q: Can I replace just a few damaged modules on my 820 sideflex chain without replacing the whole belt run?<\/div>\n
\n

Yes \u2014 this is one of the key advantages of modular plastic conveyor chain over monolithic rubber or steel chain. Individual modules on the 820 series can be removed by withdrawing the hinge rod from the damaged section and inserting a replacement module. No special tooling is required and the repair can typically be carried out during a brief production break, significantly reducing maintenance downtime on UK production lines.<\/p>\n<\/div>\n<\/div>\n

\n
Q: Where can I find a reliable 820 single row sideflex hinge chain supplier in the UK with fast delivery and custom width options?<\/div>\n
\n

We supply the 820 sideflex hinge chain to customers across the United Kingdom, including food manufacturers in Yorkshire, pharmaceutical facilities in the North West, and packaging operations in the Midlands and South East. Standard widths (82.6 mm, 114.8 mm, and 152.4 mm) are available for prompt dispatch, and we offer custom-width manufacturing for non-standard conveyor frame spacings. Contact us at sales@plastic-modular-belt.com<\/a> to discuss lead times and delivery options for your project.<\/p>\n<\/div>\n<\/div>\n

\n
Q: How does the 820 single hinge chain differ from a double hinge or multi-flex chain when used on a curved pharmaceutical packaging conveyor?<\/div>\n
\n

The 820 single hinge design pivots at one defined point per module, giving predictable and consistent lateral flex with minimal module-to-module play \u2014 ideal for pharmaceutical packaging lines where product orientation and positional stability are important during transfer. Double hinge or multi-flex chains offer tighter bend radii but introduce more surface articulation, which may not be required when your minimum curve radius is 40 mm or above. For most UK pharmaceutical conveyor applications, the 820 single hinge is the more cost-effective and dimensionally stable choice.<\/p>\n<\/div>\n<\/div>\n<\/div>\n
