This system is used for automated gravimetric weighing of filters. Any movement that is to be performed here must be lubrication-free, executed free of wear and, if wear does occur, it must be free of heavy metals, etc., that could give distorted results in the chemical analysis. The installed igus® products meet all the requirements. Those used include the iglidur® PRT rotary table bearing, plain bearings made of the materials iglidur® G, iglidur® A290 and iglidur® J, as well as a drylin® ZLW toothed belt shaft.
