Cooling and outgassing paternoster

Better pick-up

This cooling and outgassing paternoster is used in an extrusion line for hot water insulation hoses. The individual aluminium paternoster pods were to be connected with a sturdy roller chain with chain bolts in a low-cost, low-noise, easy-to-assemble and low-weight design. A solution had to be found not only for supporting the rotating movement of the pods but also for a linear movement caused by manufacturing tolerances along the chain guide. In the end, the decision was taken in favour of igubal® clip-type spherical bearings ECLM from igus®, since these can pick up the linear movement better than conventional metal bearings.
