Spider compound for flexible couplings
T-PUR® KTR

Electric drives are becoming more and more powerful, compact and dynamic. This fact has consequences for torsionally flexible couplings that compensate for misalignment, damping shocks and also to increase the service life of the drive system.

Often the environments in which gearboxes, pumps, etc. are used in are not fully known in advance. That is why well-approved spider compounds have to face their limits from time to time. In high ambient conditions spiders from PEEK or other expensive special compounds have to be used. That is why KTR have searched for a new material with a wider application range for the ROTEX® jaw couplings; having performed extensive tests in cooperation with leading manufacturers of nylon they have identified the material T-PUR®. The innovative spider compound makes the ROTEX®jaw coupling being used throughout the world more flexible for use in differing applications.
