” … the boldest and most courageous project ever”
Polymer plain bearings in hot sodium hydroxide solution at a temperature of 70 °C make it possible to halve the frictional forces and drive power while simultaneously doubling the service life. Bush conveyor chains which essentially consist of links and hardened components such as pins, bushes and rollers have been used in bottle cleaning machines for many years now. This plain bearing application in a bottle cleaning machine is used to clean around 60,000 bottles per
Due to the total grease-free environment which was ensured by means of a 2.3 percent sodium hydroxide solution, the old bushing/roller material combination (without iglidur® plain bearings) had a very high coefficient of friction. This meant that the drives distributed over several shafts were requi-

The joint aim of the development engineers of the KRONES AG and igus® GmbH companies was to halve the frictional forces and thus double the service life. This resulted in the following further advantages: ● decrease in machine downtime, 1

” … the boldest and most courageous project ever” These are the words of Peter Best describing the polymer plain bearing application in the KRONES bottle cleaning machine which won the Golden Manus award. Peter Best is the Head of Research and Development Department at KRONES AG in Flensburg, Germany, and was responsible for this project. The Manus is a joint initiative of
companies and institutions from research and business sectors. The founding initiators are igus® GmbH, the ”Industrie Anzeiger” technical journal and the Fraunhofer Chemical Technology Institute. The aim of the Manus award is to announce applications for polymer plain bearings and promote more widespread use of such bearings in the sector of new polymer materials which number amongst the key technologies of the 21st century. Further information on the Manus can be found at www.manus-wettbewerb.de.

What motivated you to develop the DryLin® W system? We noticed that with our previous linear guides we were unable to respond to certain customer enquiries. Depending on mechanical design, applications with only one rail and one slide may cause self-binding. The flexible mechanical design of the system helps to avoid this. What were the other aims? The new guide was to be very compact – but also to be able to absorb high forces. In addition, a modular mechanical design of the system was to make it possible to respond easily to an extremely wide variety of customer requirements. How is this flexibility expressed? The guide system unites two supporting round shafts in one profile. This allows optimum use of available space. In addition, there is no need for time-consuming alignment of the shafts. It is also possible to use the rails both as a onepiece version (supported double round shaft) or as a single version (supported single round shaft).

Does the flexibility also apply to the guide bearings? Yes, various versions are available even with the slides: the compact slide consists of four bearing blocks which are fitted to a mounting plate, offering the advantage of being easy to install. However, the bearing blocks may also be bolted directly onto the machine. How does DryLin® W behave under difficult ambient conditions? Dry running ensures that dirt does not adhere to the guide system. In addition, the round shaft guide ensures that only little dirt is able to come to rest on the shafts in any installation position. Where do you consider the main field of application of DryLin® W to be? We are already implementing very many applications today in the packaging industry and, in this case, primarily in labelling and hoop-banding systems and in bag forming, filling and sealing machines. Thank you for talking to us.
The length and width of the guide system are determined by the user. This modular design is greatly appreciated in the packaging industry. Low overall height allows optimum utilisation of available space.

Material iglidur® T1 which features advantageous tribological characteristics is now available for use in polymer plain bearings. In addition to the very good wear resistance and low moisture absorption, the material can also be used with soft shaft materials. The tobacco industry can now also benefit from the fundamental advantages of polymer plain bearings; 100 % freedom from maintenance and lubrication prevents both tobacco and packaging material contamination.
