Spider Overview
T-PUR® − The new heart of ROTEX®
Today‘s spider compounds are restricted within certain limits with extreme applications. For the new heart of ROTEX®, KTR
have defined new standards: T-PUR®.
For the new material KTR have improved their standards mainly with regard to fatigue strength and temperature
resistance compared to standard elastomers, keeping all other positive technical characteristics such as damping
and resistance to wear unchanged. Thus, the new material can be used with temperatures from -50 °C to +150 °C.
Subject to the higher service life the maintenance intervals and as a result the costs can be reduced.The new material
T-PUR is used for all single-parted spiders of ROTEX jaw couplings from size 14 to size 180.
