Wear test in the test laboratory

Tumble test rig: load 1N/mm2, speed 0.3m/s

To give you precise details on the wear rate of our knife edge rollers, these are examined under realistic conditions in our test laboratory. Four different iglidur materials as well as PET-P and POM-C were tested. To also make statements regarding the wear behaviour depending on the shaft materials, knife edge rollers were tested on V2A and silver steel shafts.  

Wear rates of the different iglidur materials for knife edge rollers

Load: 1MPa, speed: 0.3m/s and 0.6m/s

Knife edge rollers made of various iglidur materials running on 304 stainless steel shafts were tested. The materials were tested at speeds of 0.3m/s and 0.6m/s.

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.

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.  

Interview: Value engineering in the Food and Packaging industry

In this interview, Lars Braun, igus® Industry Manager for the Packaging Industry, talks about the importance of value engineering for the packaging, food and beverage industries, and how this method influences product development at igus.
What exactly is value engineering? In short, value engineering is a structured method of thinking that is used to develop innovations or projects. The focus lies on keeping the value or benefit as high as possible, whilst using few resources.

What are the benefits of iglidur knife edge rollers?

Withstand high temperatures, strong vibrations and more.
Resistant to dirt
Can be used even in applications involving sand, swarf and dust.



Are corrosion-free and media-resistant for use under water.
