Cam geometry consists of conductive and high-strength plastics
Maintenance-free in hazardous areas
Failsafe and non-sparking
Material of hub base: steel, aluminium, others
Standard spacers up to a shaft distance dimension of 250 mm
Assembly/disassembly by means of 4 screws only
Compensating for big shaft displacements due to the double-cardanic structure
Low restoring forces, thus increase of overall service life of all adjacent components (bearings, gaskets, etc.)
Assessed and confirmed for the use in hazardous locations in accordance with EC standard 94/9/EC (type 7.6 marked from stock, type 7.5 half shell clamping hub without feather
keyway acc. to category 3)
n contrast to other flexible couplings, the intermediate members of which are subject to bending stress and are therefore prone to earlier wear, the flexible teeth of ROTEX® couplings are subject to pressure only. 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.
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.
This type are certified and confirmed according to directive 2014/34/EU as units of category 2G/2D and thus suitable for the use in hazardous areas of zone G1, G2, D21 and D22.
