Gear boxes are the heart of each extruder drive because the sometimes extreme output torques lead to high constant loads. This is the reason why well-known manufacturers of extrusion plants are not willing to compromise about such important components – they chose Koellmann Gear.
Extruder gear boxes from Koellmann Gear have proven their worth in many thousands of extruder plants all over the world. Our cutting edge technology not only sets the standards regarding longevity and reliability but also with regard to customer satisfaction.
Our extruder gear boxes are no adapted parallel shaft gear boxes but special units „custom made“ for the respective application using high quality components. Our sub suppliers for casts, cog wheels, shafts, and bearings must meet extreme quality standards. Therefore Koellmann gear boxes are virtually 100 percent "Made in Germany", even today.
Apart from the 2 and 3 step standard line UNEX Koellmann Gear is also manufacturing a 1 step line PEES, as well as different custom-made special adaptations.
