Eye-Flex® Belt with underwelded wire spacing:

Eye-Flex® belting with underwelded wire spacing should be considered on applications where hygiene and sanitation are critical. The underwelded wire eliminates the potential bacteria traps under the spacers, springs, rings, and sleeves. This configuration makes cleaning and sanitation easy and more efficient.

Eye-Flex® Belt with rings as spacers:

This versatile variation of Eye-Flex® uses rings between the wires to increase the belt gap. By increasing the belt gap, more air will circulate around the bottom of the product. Increasing the product exposure to this additional air flow improves the efficiency of your process.

Eye-Flex® Belt with springs as spacers:

Springs help create a more dimensionally stable belt in heating or freezing applications. These belts are more dimensionally stable because the wires are able to move on the cross rod. Springs also expose a large proportion of the connecting rod for improved cleaning and sanitizing.

Eye-Flex

 

At Wire Belt we undertook a number of capital projects in the lead up to the Olympics, but there is none more unusual than the Eye-Flex® belt being used to clear the waterways around the Olympic Park. Wire Belts’ involvement with this project dates back to November 2006. The Canal and River Trust already had a weed clearing boat, and fundamental to its’ operation was the use of Eye-Flex type wire link belting.

In February 2007, the Canal and River Trust visited Wire Belt to discuss damage and maintenance problems that they were experiencing with belting from their existing supplier. Wire Belts’ John Warters was able to offer the solutions.

By changing its’ construction, the belt was made more resilient to damage and by re-engineering the boat, to use multiple narrow belts, utilization was improved. From an original belt life of two years the new belt, with about 20% repair and replacement, lasted for five years.

On May 23, 2012 the Canal and River Trust, with funding from the Environment Agency, launched two new weed boats that will service London’s waterways during the Olympics and beyond. The rivers and canals in East London formed a backdrop to the London 2012 Games, and keeping them clean and weed-free was more important than ever.

The belts for the new boat were supplied from Wire Belts’ factory, in Northern Germany, directly to the German boat builder.

Over 70 million dollars were invested in regenerating East London’s waterways, creating a wonderful legacy that stretches far beyond the summer of 2012. Rivers and canals are a prominent feature of the Olympic park.

Eye-Flex

 

Eye-Flex® belting from Wire Belt, along with Flat-Flex® belting for less demanding situations, is used in a number of weed and debris applications.  These include removing leaves from water channels at fish farms and in protecting small-scale hydro-electric generation installation from debris.

Why Choose Eye-Flex®

Built for strength. Eye-Flex® belts feature a robust modular design capable of handling high loads with minimal stretch or deflection. Each belt is custom designed to meet your process, product, and environment.

Flexible configurations. Choose from multiple drive options including cage rollers, sprockets, or chain edge for improved belt tracking and tension. Add flights, side guards, or chain links to handle orientation, containment, or spacing needs.

Clean, open design. The flat wire surface and open construction allow excellent flow-through for air, water, or product, reducing debris buildup and simplifying sanitation.

Proven reliability. From heating to freezing to heavy product transport, Eye-Flex® performs in tough applications where other belts can’t.

Eye-Flex® Configuration Options 

Without Spacers

Eye-Flex® can be built without spacers to provide maximum product support.The clean, straight modular form eliminates welded cross-supports, making it easier to clean and repair. This version is widely used in food processing due to its sanitary design and flat carrying surface.

With Underwelded Wire Spacing

Designed for food contact applications, this configuration removes springs, sleeves, and rings that could trap debris. The underwelded wire layout supports sanitation protocols, allowing easier, more effective cleaning in environments where contamination must be minimized.

Optional Features

  • Side guards to contain product or prevent overflow
  • Cross flights for lifting, spacing, or indexing
  • Chain edges (hollow pin, loose link, or side chain) for enhanced drive control

Every Eye-Flex® belt is engineered to order. Our team works closely with you to ensure your belt design meets your throughput, sanitation, and layout needs.

Frequently Asked Questions

What makes Eye-Flex® a heavy duty, modular conveyor belt?

Eye-Flex® is engineered for high loads and tough conditions using durable stainless steel and a customizable modular layout. Its construction minimizes deflection and allows for precise configurations. Reach out to our team to explore options for your application.

Is Eye-Flex® suitable for washdown or sanitation-heavy environments?

Yes. Eye-Flex® is often used in food and hygiene-sensitive industries. The open mesh and optional underwelded design reduce bacteria traps and support quick, effective cleaning. Get in touch to review sanitation specs for your line.

Can Eye-Flex® handle extreme temperatures?

Absolutely. The spring-spaced configuration offers thermal flexibility, making Eye-Flex® ideal for freezing, heating, or drying lines. The belt maintains structure while allowing for expansion and contraction. Contact us to discuss temperature-specific setups.

What industries use Eye-Flex® belts most?

Eye-Flex® is trusted in food processing, meat and poultry, seafood, baking, industrial washdown, and freezer lines, anywhere that requires a heavy duty, modular conveyor belt built to last. Speak with a specialist to find your match.

Can the belt be repaired easily?

Yes, Eye-Flex®’s modular form allows for low-cost repair by replacing individual rods or segments. Talk to our service team about maintenance best practices.
