Gear coupling ,Bush coupling : KTR



Product features

  • Flexible, vibration-reducing

  • Axial plug-in, easy assembly

  • Fail-safe

  • Torques up to 35,000 Nm

  • Reduced maintenance, easy to inspect visually

  • Standard material for spiders: T-PUR®


     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.



Product features

  • Material combination: nylon / steel

  • Compensation for shaft misalignment: axial, radial, angular

  • Axial plug-in, simplified assembly

  • Operative range -25° C to +100° C

  • Torque from 5 to 2,500 Nm


     The material combination of steel hubs and polyamide sleeves allows for maintenance-free continuous operation with very low friction on the teeth.

     Due to the double cardanic operation of BoWex® couplings restoring forces may be neglected in case of angular and radial displacements and periodic fluctuations in angular velocity do not arise.

     BoWex® couplings can be assembled both vertically or horizontally with no need for any special assembly tools.

Behavior of friction and wear

     The smooth and hard surface (crystalline structure) and the high thermal stability and resistance to lubricants, fuels, hydraulic fluids, dissolvents, etc. make polyamide an ideal material for components stressed by sliding, particularly for the coupling production.

While any metallic materials tend to "corrode" in case of dry running, slide combinations with polyamide and steel are operative without any lubrication and maintenance.
