KTR precision joints consist of a joint center piece and two hubs that are interlinked by straps. The bearing of the joint heads is made by plain bearings with precision joints type G and GD. The plain bearings type G and GD limit the maximum permissible speed to 1,000 rpm. The maximum diffraction angle of KTR’s cardan shafts per joint is 45°.
This bearing allows cardan shafts compared to other coupling types to compensate for significantly larger angular shaft displacements. Double joints that have two bearings are able to offset radial displacement in addition.
