Now KTR has an innovation for the large ROTEX® coupling: The patented standard ROTEX® DZ does not have the wellknown star-shaped elastomer spider, but the elastomer spider is rather divided up into individual segments with two teeth each. This new design is the new standard for the series ROTEX® 100 to ROTEX® 180. The well-known one-parted spider is only supplied on special request in these sizes. The ROTEX® DZ spider segments are offered as flexibly damping components in the well-known kinds of standard Shore hardness 92 Sh-A and 95 Sh-A.
