Product Description:
1873TAB Rubber-Top Side-Flex Tabletop Chain fitted with curve-retention tabs. This anti-lift structure stops chain floating and derailment when navigating tight spiral bends, while its non-marking high-grip rubber overlay keeps packages from slipping during uphill, downhill and accumulation conveying for spiral coolers and accumulator systems.
Applications:
• Spiral accumulators for buffer storage between production processes
• Spiral cooling tunnels for bread, pastries, chocolate and ready meals
• Spiral elevators for vertical feeding and discharging of packaged goods
• Horizontal curved transfer conveyors to redirect carton flow
• Incline & decline accumulation lines with start-stop merging
• End-of-line packaging: case packing, carton sealing and palletising preparation
• Food, bakery, dairy, confectionery, ready meal and pharmaceutical packaging
• Premium packaged goods, printed cartons and labelled products (non-marking)
• Retrofit and spare chain replacement for existing spiral conveyors

Advantages:
This 1873TAB rubber-top side-flex tabletop chain is purpose-built to resolve recurring operational challenges encountered on spiral accumulation, spiral elevation and curved material handling conveyors. Its molded curve-retention tabs lock securely into the guide track as the chain navigates tight-radius bends. This design eliminates chain lift, floating and derailment, the most frequent causes of unplanned stops and jams in spiral systems, delivering steady, predictable performance during continuous production cycles.
The vulcanized rubber top overlay provides reliable high friction while remaining non-marking. This characteristic makes it highly suitable for uphill, downhill and start-stop conveying scenarios, where packages, cartons and packaged goods must stay positioned without sliding or shifting. Unlike low-friction plain acetal chains, the rubber surface maintains consistent grip even with fluctuating line speeds and accumulation pressure.
The chain base is manufactured from high-grade acetal copolymer. It offers excellent wear resistance, chemical resistance and stable dimensional performance over long service hours. It operates with low noise, even under heavy, continuous duty, which is ideal for packaging facilities, food processing lines and cold spiral cooling applications.
Built to the standard 1.5-inch pitch, this 1873TAB chain maintains full interchangeability with mainstream equivalent tabletop chains on the market. We supply a broad selection of standard widths, and we can cut chain segments to your exact required length. Installation and component replacement are straightforward, minimizing maintenance time and labour cost for your conveyor teams.
Every batch is inspected before shipment to guarantee consistent quality and precision. Whether you are building a new spiral conveyor or replacing worn-out existing chain, this rubber-top side-flex chain offers a dependable, cost-effective solution for your curved conveying layouts.

1873TAB Rubber-Top Side-Flex Tabletop Chain | Curve-Retention Tab Spiral Chain
The 1873TAB RT side-flexing tabletop chain is designed for spiral accumulators, spiral elevators and curved conveyor runs. Integrated curve-retention tabs engage with the guide track through bends to stop chain lift and derailment, delivering consistent performance on tight-radius curves.
1. Rubber-Top Surface: High-friction, non-marking rubber overlay. Well suited for uphill, downhill and start-stop conveying to hold packages securely.
2. Side-Flex Construction: Permits horizontal curving, ideal for spiral conveyor layouts.
3. Curve-Retention Tabs: Anti-lift tab geometry eliminates chain float on bends.
4. Standard Pitch: 1.5 in (38.1 mm), compatible with standard 63 base roller chain.
5. Material: Acetal chain base + durable rubber overlay. Wear-resistant, low noise and simple to maintain.
6. Typical Applications: Spiral accumulation conveyors, spiral coolers, case packing and material handling lines.
We stock this 1873TAB rubber-top side-flex chain in a full range of widths. Custom cut lengths and samples are available on request. Reach out to us for technical drawings and datasheets.
