  • a roller tube fulfills several tasks. Each of these tasks must be re-evaluated in every application. Dead weight, external loads, bearing clearances, surface stress, looping material and transmission of torques are only keywords for extensive considerations, assessments and material decisions.
  • roller made of steel material covers this entire spectrum of possibilities. In terms of construction, it is designed as a full steel tube or cast component. With the industrial use of aluminum, rollers were also made from this material. That was not enough. The task was tackled again with chemical materials and composite materials made from fibers and synthetic resins were developed. This path is that of using high-quality raw materials. In aircraft and vehicle construction, which has always had special requirements regarding the weight of the components, consistent developments have led to products that combine density with excellent stability. The considerations according to the invention went in this direction.
  • a light, dimensionally stable roller tube is a composite construction, even under load. Bore and roller outer surface have a function. Both surfaces therefore require a closed surface. In the simplest case, they are a tube that can be thin-walled. A construction is required between the inner and outer tube, which must correspond to the range of applications outlined at the beginning. Ultimately, this construction also brings the stability and mass savings that are required according to the task.
