This gives the additional advantage of the individual teeth being able to accept considerably higher loads. The elastomer parts show deformation with load and excessive speeds. Sufficient space for expansion should be ensured. The maximum torsion angle with ROTEX® couplings of any size amounts to 5°. They can be fitted both horizontally and vertically. T-PUR® – The new heart of ROTEX® With the temperature-resistant polyurethane T-PUR® of KTR the properties of the ROTEX® have been optimized importantly. T-PUR is a much more temperature-resistant and has a longer service life than polyurethane material. From the visual point of view we have characterized the material T-PUR® by the colours orange (92 Shore A), purple (98 Shore A) and pale green (64 Shore D). The previous spiders made from polyurethane in yellow, red and natural white with green ends will still be available.
