Knife Edge Rollers

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!

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.

The knife edge rollers are ideal for these conveyors as they allow the following:

Easy gliding
Low coefficient of friction
No lubrication.
Hard wearing
Easy to replace.

Use in food processing

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.
