In this packing machine, the boxes are discharged at the end of the process via the ejector unit by means of a pivoting movement. The disadvantage of the self-aligning ball bearings originally used was that they required regular lubrication. The oil also soiled the packaging some of the time. Now that the ball bearings have been replaced by igubal® pivoting bearings from igus®, soiling is outdated. Because the pivoting bearings are absolutely lubricant-free.
