The manus award is a joint initiative which the plastics specialist igus announces every two years. More than 3,000 contestants from across the globe have entered the competition in recent years, which honours the creative use of polymer plain bearings in industrial applications. This year, the manus award celebrates its tenth anniversary. A good reason to look back: what has become of the last nine winners and their projects? The Industrieanzeiger made enquiries.
To make sure bottles are cleaned, Krones AG makes bottle cleaning machines for the beverage industry. In the machines, conveyor chains transport the bottle carriers. The bottle carriers go through different treatment areas. The main cleaning takes place in 80°C soda lye. To design the conveyor chains as a smooth running chain even under challenging conditions, Krones AG used plain bearings made from a customised high-performance polymer. Today, the materials iglidur J and iglidur X6 are the best choice to take on all challenges in practice. The lubrication-free and dirt-resistant polymer plain bearings were produced by igus in Cologne with special geometries via injection moulding. They minimise the coefficient of friction of the washing chain significantly and hence increase the energy efficiency and durability of the system. These important criteria led to Krones AG winning the first gold manus award in 2003. We discussed the project with Mr. Michael Siegmund, Head of Cleaning Technology at Krones AG.
