Knife edge rollers are small rollers which form a continuous gliding edge on conveyor belts. It enables product to glide smoothly between belts. Unsurprisingly they are commonly found on the edge of conveyors, providing a lubrication-free and precise guide system.
igus® has developed a range of knife edge rollers in their iglidur® materials. These rollers offer a tight deflection radius and require a very low amount of drive power. They are easily assembled and are extremely cost effective. If we can't offer you a standard roller to meet your requirements we can custom machine one!

What are the benefits of iglidur knife edge rollers?
Robust Withstand high temperatures, strong vibrations and more.
Resistant to dirt Can be used even in applications involving sand, swarf and dust.
Corrosion-free Are corrosion-free and media-resistant for use under water.
Hygienic Do not require external lubrication and are FDA-compliant.
Light Lighter than comparable guide rollers with metal
Versatile Different materials allow for an exact customisation to your application.
Knife edge roller applications
Krones relies on iglidur knife edge rollers
Regarding Variopac Pro, a fully automatic all-rounder packaging system, Krones faced a problem in 2005: the system's performance had to be increased by 20 packages per minute. Hence, there was an urgent need for action during the deflection of the conveyor belts. Originally, metal rollers with needle roller bearings were used here; however, they couldn't fulfil the higher performance requirements and were cost-intensive. When looking for an alternative, Krones Design Engineer Jürgen Werner came upon the products from igus GmbH.
It is not only raw bakery products that present the machine manufacturer in the food sector with considerable challenges. If two conveyor belts are butt-jointed to each other, the radii of the guide rollers result in a gap between the two belts. The risk: sensitive products, such as raw pasta products, simply slide into the gap between the conveyor belts.
To transfer these products safely from belt to belt, the deflection radii of the conveyor belts and the gap between the belts must be kept as small as possible.
Conveyor rollers are essential in the Food and Packaging industry. Having a large range of FDA and EU compliant knife edge rollers allows customers to have peace of mind that there is no contamination. The iglidur® A180, A350 and A250 knife edge rollers are all FDA/ EU 10/2011 compliant. All FDA products have full certification and can be found on the website.
