Title story
pack @ Lubrication-free igus® machinery elements are now being used in many different applications in the packaging industry.
The German company Krones AG, for instance, has replaced the conventional linear guides in its bottling-filling systems with maintenance-free iglidur® plastic plain bearings. As a result, high production costs and production losses can now be ruled out (title story). Similarly, the tribooptimised polymer plain bearings which cope with extremely adverse conditions in the bag forming, filling and sealing machine of the German company Hastamat Verpackungstechnik GmbH (page Lars Braun, Branch 3). Already in the Manager Packaging development phase, igus was integrated as system supplier – which corresponds to the present trend toward complete solutions. A second trend – which could also be recognised at the Interpack show in Düsseldorf – is the subject of hygienic design. Here in numerous applications, our lubricant-free plastic plain bearings help keep hygienically disturbing substances away from packing goods.
We look forward to talking to you about these and other subjects! In autumn you will find igus®, among others, at the „Brau“ exhibition in Nuremberg , at the „Emballage“ in Paris, at the „PPMA“ in Birmingham, at the „China Brew“ in Shanghai, at the „Propak Cape“ in Cape Town and at the Japanese „Tokyo Packaging“ show. Yours sincerely,

Hygienic design: polymer bearings instead of conventional linear guides
Like many other beverage producers, Krones AG, in Neutraubling, relies on modern block systems for the purpose of filling PET bottles. Furthermore, the individual system component complement each other perfectly. Here iglidur® plastic bearings have become an important factor. They fulfil the requirements of the customer specifications, all hygiene regulations, and cost much less.
The pull-back star developed by Krones combines components of the filling system and must fulfil high aseptic and hygienic requirements. It is also constantly exposed to moist, chemically aggressive ambient conditions. The linear guides and curve rollers installed in the predecessor models were suscep- Pull-back star, installed in an aseptic filler tible to corrosion, difficult to clean, and a hygiene risk because of the required lubricants. That is why Krones has now changed over to the use of lubrication- and maintenancefree polymer bearings from igus®. Here iglidur® J bearings and high-temperature-resistant iglidur® X plain bearings are now being used. They offer minimal heat relaxation, high pressure resistance and dimensional accuracy together with good heat dissipation and minimal creep inclination. Furthermore, they are insensitive to chemicals.
